Answer:
a =-6
Step-by-step explanation:
4a+5=2+3.5a
Subtract 3.5a from each side
4a-3.5a+5=2+3.5a-3.5a
.5a +5 = 2
Subtract 5 from each side
.5a +5-5 = 2-5
.5a = -3
Divide each side by .5
.5a/.5 = -3/.5
a =-6
Answer:
(x) = 
Step-by-step explanation:
Let y = f(x) and rearrange making x the subject, that is
y = 7x - 6 ( add 6 to both sides )
y + 6 = 7x ( divide both sides by 7 )
x = 
Change y back into terms of x, hence
(x) =
