Question

Given f(x)=2x-10 determine the value if f(x)=8

Answer 1

Answer:

f(x)=2x-10 ______(given)

f(x)=8 _______(given)

Therefore, according to the above problem

2x-10=8

2x=10+8

2x=18

x=18/2

x=9

9 is the right answer.

Answer 2

Answer:

We have given that...

f(x) = 2x - 10

f(x) = 8

So..

2x - 10 = 8

2x = 8 + 10

2x = 18

x = 18/2

x = 9 ✓✓✓
