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
