Question

A+bx=z
get x by its self

Answer 1

x =
`(z)/(b) -(a)/(b)`

Explanation:

a + b(
`(z)/(b) -(a)/(b)`) = z

a + z - a = z

a - a + z = z

z = z

This is true.

Answer 2

Answer: x=(z-a)/b

Explanation:

First subtract a from both sides to begin isolating x on its side of the equation. This gives you bx=z-a. Next, divide b from both sides to finish isolating x. This gives you x=(z-a)/b
