1. Liam is solving the following equation 12a - 4(5a - 1) = 2(3a + 6) - 4a. The result of each step of his solution is shown below.
12a - 4(5a - 1) = 2(3a + 6) - 4a
12 - 20a + 4 = 6a + 12 - 4a
-8a + 4 = 2a + 12
-6a = 8
a = -4/3
Describe the error AND solve correctly.

Step-by-step explanation:

Liam did not include 12a in line- two

Step one:

given the expression

let us trace the solution line by line

collect like terms

divide both sides by -10 we have
