Steps for finding the solution

We have 4x + 4 = 9

First, we move the non x terms to the RHS of the equation. To do this, we subtract 4 from both sides.

Note: if a = b, then a - c = b - c

Therefore, 4x + 4 - 4 = 9 - 4

or, 4x = 5

Next, divide both sides by 4, which is the coefficent of x

Note: if a = b, then a ÷ c = b ÷ c

4x/4 = 5/4

x = 5/4 or, x = 1.25

Solve another equation
