Question

If f(x)=10x+3 whar is the value when f(x)=19

Answer 1

x = 1.6

Explanation:

Given f(x) = 10x + 3 and f(x) = 19, then equate right sides, that is

10x + 3 = 19 ( subtract 3 from both sides )

10x = 16 ( divide both sides by 10 )

x = 1.6

Answer 2

• x = 1.6

Explanation:

Given

• f(x)=10x+3

and

• f(x) = 19 ⇒ x = ?

Solution

• 10x + 3 = 19
• 10x = 16
• x = 16/10
• x = 1.6
