Solve the equation and check.
13y÷6=20y-1

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?

Olivia uses the work below to determine 55% of 720 which explains the error in olivia’s solution
