Linear Equations - Exercise 1

Justify each step below where the equation  x/3 + 3(x + 5) = 4x - 1 is solved with solution  x = 24.

 STATEMENT JUSTIFICATION x/3 + 3(x + 5) = 4x - 1x/3 + 3x + 15 = 4x - 1 3(x/3 + 3x + 15) = 3(4x - 1) x + 9x + 45 = 12x - 3 10x + 45 = 12x - 3 48 = 2x 24 = x Given___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________
