Question

Which are possible first steps in solving the equation 4x + 3 = 18?

Answer 1

x = 3.75

Explanation:

4x + 3 = 18

4x = 18 - 3

4x = 15

x = 15 : 4

x = 15/4

x = 3.75

Answer 2

x = 3.75

Explanation:

4x + 3 = 18

The first step in this equation is to subtract 3 from both sides. (Or subtract 18 form both sides but then we would still have to put it on the other side)

4x + 3 - 3 = 18 - 3

4x = 15

Then divide by 4

x = 15/4 = 3.75
