7/8 - 3/8 = 4/8 ( When Simplified it is 1/2)
Or
18/20 - 8/20 = 10/20 ( Also when Simplified it is 1/2)
Answer:
see explanation
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x + 4 ( multiply through by 2 to clear the fraction )
2y = x + 8 ( subtract 8 from both sides )
2y - 8 = x
Change y back into terms of x with x = (x) , then
(x ) = 2x - 8
(4) = 2(4) - 8 = 8 - 8 = 0
