Question

If f(x) = 2(3x - 5) when f(x) = 74, what is
the value of x?​

Answer 1

f(×)=2(3×-5)

f(×)=74

×

Explanation:

2(6×2)=32

Answer 2

x = 14

Explanation:

Given f(x) = 2(3x - 5) and f(x) = 74, then equate right sides

2(3x - 5) = 74 ( divide both sides by 2 )

3x - 5 = 37 ( add 5 to both sides )

3x = 42 ( divide both sides by 3 )

x = 14
