What is an example of a equation?

In algebra an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value. … For instance 3x + 5 = 14 is an equation in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign.

What is a simple equation?

A simple equation refers to a mathematical equation that expresses the relationship between two expressions on both sides of the ‘equal to’ sign. This category of an equation consists of a variable usually in the form of x or y. … Variable means an unknown factor in an equation that a simple equation aims to find out.

What is simple equation examples?

A linear equation that involves only one variable is known as a simple equation or a linear equation in one variable. For example 3x+2=23 x=7 2x+6=3x–4 etc. are simple equations.

How do you do equations for kids?

How does an equation look like?

An equation is a mathematical sentence that has two equal sides separated by an equal sign. 4 + 6 = 10 is an example of an equation. We can see on the left side of the equal sign 4 + 6 and on the right hand side of the equal sign 10. … For example 12 is the coefficient in the equation 12n = 24.

  • Area of rectangle = length × width.
  • The perimeter of a square = 4 × side length.
  • Area of square =Side length × side length.
  • The volume of cuboid = length × width × height.
  • Profit = Selling price – cost price.
  • Loss = Cost price – selling price.

What is solution of an equation?

A solution is an assignment of values to the unknown variables that makes the equality in the equation true. … For example the equation x + y = 2x – 1 is solved for the unknown x by the expression x = y + 1 because substituting y + 1 for x in the equation results in (y + 1) + y = 2(y + 1) – 1 a true statement.

What is the equation form?

The standard form for linear equations in two variables is Ax+By=C. For example 2x+3y=5 is a linear equation in standard form. When an equation is given in this form it’s pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

What is a one step equations?

A one-step equation is an algebraic equation you can solve in only one step. You’ve solved the equation when you get the variable by itself with no numbers in front of it on one side of the equal sign.

What is the golden rule for solving equations?

Do unto one side of the equation what you do to the other!

If we put something on or take something off of one side the scale (or equation) is unbalanced. When solving math equations we must always keep the ‘scale’ (or equation) balanced so that both sides are ALWAYS equal.

What are the steps to solving equations?

The following steps provide a good method to use when solving linear equations.
  1. Simplify each side of the equation by removing parentheses and combining like terms.
  2. Use addition or subtraction to isolate the variable term on one side of the equation.
  3. Use multiplication or division to solve for the variable.
