zavuch27 [327]

Simplifying X + 4y = 36 Solving X + 4y = 36 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-4y' to each side of the equation. X + 4y + -4y = 36 + -4y Combine like terms: 4y + -4y = 0 X + 0 = 36 + -4y X = 36 + -4y Simplifying X = 36 + -4y
