Well I don't know !
Let's get together and figure it out. Are you with me ?
You said that 8x - 2 = -9 + 7x
Add 2 to each side: 8x = -7 + 7x
Subtract 7x from each side: x = -7
Now that wasn't so bad, was it ?
14x-21y+42 should be your answer. hope it helps :)
158+ 148+ 32 + x = 360
x= 22
Answer:
see explanation
Step-by-step explanation:
(a)
let y = f(x), that is
5x + 3 = y
Rearrange making x the subject
Subtract 3 from both sides
5x = y - 3 ( divide both sides by 5 )
x = (y - 3) / 5, hence
(x) = (x - 3) / 5
(b)
(8) = (8 - 3) / 5 = 5/ 5 = 1
