To solve this for x.....

3x + (-4) = 2x + 9

3x - 4 = 2x + 9

Add 4 to both sides of the equation.

3x = 2x + 9 + 4

3x = 2x + 13

Subtract 2x from both sides of the equation.

3x - 2x = 13

x = 13

12 = $$\frac67$$x

Multiply both sides of the equation by $$\frac76$$

12 * $$\frac76$$ = $$\frac67$$x * $$\frac76$$

14 = x
