If a-7=b (x+2) then x=?

X = (a - 7) / b - 2

Step-by-step explanation:

When this kind of question arises, what we are expected to do is to make x the subject of formula.

Reason because we have up to three unknown in the equation including x.

So let's make x the subject of the formula.

a-7=b (x+2)

a - 7 = bx + 2b

a - 2b - 7 = bx

a-7 - 2b = bx

Dividing through by b

(a-7) / b - 2 = x

X = (a - 7) / b - 2
