Add 6 to both sides
-102 + 6 = -2(6 - 7x)
Simplify -102 + 6 to -96
-96 = -2(6 - 7x)
Divide both sides by -2
-96/-2 = 6 - 7x
Two negatives make a positive
96/2 = 6 - 7x
Simplify 96/2 to 48
48 = 6 - 7x
Simplify 48 - 6 to 42
42 = -7x
Divide both sides by -7
-42/7 = x
Simplify 42/7 to 6
-6 = x
Switch sides
Answer: x = -6
