z = 8 + 6x - px Subtract 8 from both sides
z - 8 = 6x - px Factor the x out of 6x - px
z - 8 = x (6 - p) Divide both sides by (6 - p)
= x Switch the sides to make it easier to read
x = <span> </span>
z - 8 = 6x - px Factor the x out of 6x - px
z - 8 = x (6 - p) Divide both sides by (6 - p)
x = <span>
