Liam is solving the equation 7x + 6(x + 3) = 83 His steps are shown below. What mistake did Liam make while solving?
7x + 6(x + 3) = 83
7x + 6x + 3 = 83
13x + 3 = 83
13x + 3 - 3 = 83 - 3
13x = 80
(13x)/13 = 80/13
x = 6 2/13
(1 point)
Liam did everything correctly.
Liam should have added 3 to both sides of the equation rather than subtracting.
Liam forgot to distribute the 6 to the 3.
Liam should have subtracted 13 from both sides of the equation rather than dividing.
