Sandra graphed the system of equations that can used to solve x^3 - 2x^3-11x + 12= x^3 - 13x - 12.

Ily begins solving the equation 4(x – 1) – x = 3(x + 5) – 11. her work is shown below. 4(x – 1) – x = 3(x + 5) – 11 4x – 4 – x = 3x + 15 – 11 3x – 4 = 3x + 4 how can her partial solution be interpreted?
