5x - 12 - 6x = -10x + 7 - 1
Combine like terms:
- x - 12 = - 10x + 6
Add 10x to both sides:
9x - 12 = 6
Add 12 to both sides:
9x = 18
Divide both sides by 9:
x = 2

Multiply both sides by x to get the "x" terms on the same side of the inequality: x−6<4
Multiply both sides by x to get the "x" terms on the same side of the inequality: x−6<4
Divide both sides of the inequality by x to simplify: 1−6x<4
x<6
Divide both sides of the inequality by x to simplify: 1−6x<4
x<6
Multiply both sides by 4 to clear the inequality of fractions: 4x−24<x
Multiply both sides by 4 to clear the inequality of fractions: 4x−24<x
Divide both sides of the inequality by 4 to simplify: x4−32<x
Divide both sides of the inequality by 4 to simplify: x4−32<x
