Answer:

x = 1.5

Explanation:

Step 1: Distribute

-3(2 - 5x) = 3x + 12

(-3 * 2) + (-3 * -5x) = 3x + 12

-6 + 15x = 3x + 12

Step 2: Subtract 3x from both sides

-6 + 15x - 3x = 3x + 12 - 3x

-6 + 12x = 12

Step 3: Add 6 to both sides

-6 + 12x + 6 = 12 + 6

12x = 18

Step 4: Divide both sides by 12

12x / 12 = 18 / 12

x = 1.5

Answer: x = 1.5
