Explanation:

1. Step1: Isolate term with x

$8x = 63 - 15$

Step1: Calculate right side

$8x = 48$

Step2: Solve for x

$x = \frac{48}{8} = 6$

2. Step1: Isolate term with x

$9x = 23 + 13$

Step1: Calculate right side

$9x = 36$

Step2: Solve for x

$x = \frac{36}{9} = 4$

3. Step1: Isolate term with x

$135 - 25 = 2x$

Step1: Calculate left side

$110 = 2x$

Step2: Solve for x

$x = \frac{110}{2} = 55$

4. Step1: Isolate term with x

$32x = 33 + 31$

Step1: Calculate right side

$32x = 64$

Step2: Solve for x

$x = \frac{64}{32} = 2$

5. Step1: Isolate term with x

$12x = 68 + 16$

Step1: Calculate right side

$12x = 84$

Step2: Solve for x

$x = \frac{84}{12} = 7$

6. Step1: Isolate term with x

$7x = 136 - 115$

Step1: Calculate right side

$7x = 21$

Step2: Solve for x

$x = \frac{21}{7} = 3$

7. Step1: Isolate term with x

$4x = 82 - 14$

Step1: Calculate right side

$4x = 68$

Step2: Solve for x

$x = \frac{68}{4} = 17$

8. Step1: Isolate term with x

$2x = 34 + 56$

Step1: Calculate right side

$2x = 90$

Step2: Solve for x

$x = \frac{90}{2} = 45$

9. Step1: Isolate term with x

$3x = -\frac{19}{2} + \frac{9}{2}$

Step1: Calculate right side

$3x = -\frac{10}{2} = -5$

Step2: Solve for x

$x = \frac{-5}{3x}$ → $3x=-15$ → $x=-5$

10. Step1: Isolate term with x

$-\frac{1}{4}x = 10 - 12$

Step1: Calculate right side

$-\frac{1}{4}x = -2$

Step2: Solve for x

$x = (-2) \times (-4) = 8$ → $x=-8$

11. Step1: Isolate term with x

$6x = 11.19 - 4.59$

Step1: Calculate right side

$6x = 6.6$

Step2: Solve for x

$x = \frac{6.6}{6} = 1.1$

12. Step1: Isolate term with x

$2x = 25.68 + 6.32$

Step1: Calculate right side

$2x = 32$

Step2: Solve for x

$x = \frac{32}{2} = 16$
