Consider the following formula

ax - bx + y = z

which of the following represents the formula that could be used to find x?

a.) x= z-y/a-b

b.) x=a-b/z-y

c.) x= z-y/b-a

d.) x=y-z/b-a

Hello
This question requires us to change the subject of a formula. This can be achieved by following the order of operations in reverse. First, isolate the terms with our variable of interest, x:
ax - bx = z - y
Then, we take x out as it is being multiplied to both a and b:
x(a - b) = z - y
Dividing (a - b) on both sides, we get:
x = (z - y) / (a - b)
Thus, the answer is A
