r^2-v=42

Solution for r^2-v=42 equation:

Simplifying
r2 + -1v = 42

Solving
r2 + -1v = 42

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add 'v' to each side of the equation.
r2 + -1v + v = 42 + v

Combine like terms: -1v + v = 0
r2 + 0 = 42 + v
r2 = 42 + v

Simplifying
r2 = 42 + v

Reorder the terms:
-42 + r2 + -1v = 42 + v + -42 + -1v

Reorder the terms:
-42 + r2 + -1v = 42 + -42 + v + -1v

Combine like terms: 42 + -42 = 0
-42 + r2 + -1v = 0 + v + -1v
-42 + r2 + -1v = v + -1v

Combine like terms: v + -1v = 0
-42 + r2 + -1v = 0
