Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-2x' to each side of the equation.
8a + 2ax + 2x + -2x = 142 + -2x

Combine like terms: 2x + -2x = 0
8a + 2ax + 0 = 142 + -2x
8a + 2ax = 142 + -2x

Reorder the terms:
-142 + 8a + 2ax + 2x = 142 + -2x + -142 + 2x

Reorder the terms:
-142 + 8a + 2ax + 2x = 142 + -142 + -2x + 2x

Combine like terms: 142 + -142 = 0
-142 + 8a + 2ax + 2x = 0 + -2x + 2x
-142 + 8a + 2ax + 2x = -2x + 2x

Combine like terms: -2x + 2x = 0
-142 + 8a + 2ax + 2x = 0

Factor out the Greatest Common Factor (GCF), '2'.
2(-71 + 4a + ax + x) = 0

Ignore the factor 2.
Subproblem 1
