Answer:
x = (z-y)/(a-b)
Step-by-step explanation:
Given ax-bx+y=z, we are asked to isolate x. To do so, first take common factor between the first and the second terms
ax-bx+y=z
(a-b)*x+y = z
Then, isolate the x term by subtracting y at both sides
(a-b)*x+y-y = z-y
(a-b)*x = z-y
Finally, divide by (a-b) at both sides
(a-b)*x/(a-b) = (z-y)/(a-b)
x = (z-y)/(a-b)
