Question

What is the solution: 12 = 6 –5x + 3x

Answer 1

Answer:

x = -3

Step-by-step explanation:

Step 1: Write equation

12 = 6 - 5x + 3x

Step 2: Solve for x

1. Combine like terms:                    12 = 6 - 2x
2. Subtract 6 on both sides:            6 = -2x
3. Divide -2 on both sides:               -3 = x
4. Rewrite:                                         x = -3

Step 3: Check

Plug in x to verify it's a solution.

1. Substitute:               12 = 6 - 5(-3) + 3(-3)
2. Multiply:                   12 = 6 + 15 - 9
3. Add:                         12 = 21 - 9
4. Subtract:                  12 = 12
