Question

I know how to solve this but i don’t understand what it means by “what is x if g(x) is 150”??

Answer 1

Explanation:

The rule is 5x - 15

g(x) = 150 which is the same thing as saying

y = 5x - 15

y = 150

150 = 5x - 15 Add 15 to both sides

165 = 5x Divide by 5

35 = x

Remember that g(x) has all the properties of y
