Question

If f(x) = 2x+ 3 and f (x) = 35, then what is x?

Answer 1

Answer: x = 16

Step-by-step explanation:

f(x) = 2x + 3

f(x) = 35

35 = 2x + 3

or

2x + 3 = 35

subtract 3 from both sides

2x = 32

divide both sides by 2

x = 16

Answer 2

Given,

f(x) = 2x+ 3

and

f(x) = 35

Therefore,

2x + 3 = 35

2x = 35 - 3

2x = 32

x = 32/2

x = 16
