Explanation:

Step1: Solve - 5x = - 25

Divide both sides by - 5. $x=\frac{-25}{-5}=5$

Step2: Solve $\frac{x}{6}=3$

Multiply both sides by 6. $x = 3\times6=18$

Step3: Solve $\frac{x}{8}=2$

Multiply both sides by 8. $x=2\times8 = 16$

Step4: Solve 3x = 18

Divide both sides by 3. $x=\frac{18}{3}=6$

Step5: Solve $\frac{5x}{3}=\frac{-30}{9}$

Cross - multiply: $5x\times9=-30\times3$. Then $45x=-90$. Divide both sides by 45, $x=\frac{-90}{45}=-2$

Step6: Solve 7x = 49

Divide both sides by 7. $x=\frac{49}{7}=7$

Step7: Solve - 2x = 34

Divide both sides by - 2. $x=\frac{34}{-2}=-17$

Step8: Solve $\frac{4x}{3}=-16$

Multiply both sides by 3: $4x=-16\times3=-48$. Then divide both sides by 4, $x=\frac{-48}{4}=-12$

Step9: Solve - 4x=-40

Divide both sides by - 4. $x=\frac{-40}{-4}=10$

Answer:

For - 5x = - 25, x = 5; for $\frac{x}{6}=3$, x = 18; for $\frac{x}{8}=2$, x = 16; for 3x = 18, x = 6; for $\frac{5x}{3}=\frac{-30}{9}$, x=-2; for 7x = 49, x = 7; for - 2x = 34, x=-17; for $\frac{4x}{3}=-16$, x=-12; for - 4x=-40, x = 10
