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
