Question

Given g(x) = 2x – 1, solve for x when g(x) = 3.

Answer 1

Answer: x = 2

Step-by-step explanation:

Set g(x) = 3

3 = 2x - 1
Add 1 to both sides
4 = 2x
Divide by 2 on both sides
x = 2

Answer 2

x = 2

Step-by-step explanation:

g(x) = 2x - 1

g(x) = 3

2x - 1 = 3

Add 1 to both sides;

2x = 4

Divide both sides by 2;

x = 2
