Step-by-step explanation:
-px + r = 8x -2
Step 1: Add -8x to both sides.
-px + r + -8x = 8x - 2 + -8x
-px + r - 8x = 2
Step 2: Add -r to both sides.
-px + r - 8x + -r = -2 + -r
-px - 8x = -r - 2
Step 3: Factor out variable x.
x(-p - 8) = -r - 2
Step 4: Divide both sides by -p - 8.
x(-p - 8) = -r - 2
-p - 8 -p - 8
Answer
x = r + 2
p + 8
