Introduction to solving multi step equation:

If two expressions are in equal, then it is called as an equation. When we add, subtract, multiply or divide the similar number on both sides of the equation, the equation does not change. More than two steps are used to solve the equation is called as multi step equation. Now, we are going to see some of the problems on solving multi step equations.

Solving Multi Step Equations Problems:

Example problem 1:

Solve for the variable y: -20 = 3 (2 y + 8) + 4

Solution:

-20 = 3 (2y + 8) + 4

Eliminate the parentheses,

-20 = 3 (2 y) + 3 (8) + 4

-20 = 6 y + 24 + 4

-20 = 6y + 28

Subtract 28 on both sides of the equation

-20 - 28 = 6 y + 28 – 28

-48 = 6 y

Divide by 6 on both sides of the equation

-8 = y

So, the answer is y = -8.
