What is the solution: 12 = 6 –5x + 3x

x = -3

Step-by-step explanation:

Step 1: Write equation

12 = 6 - 5x + 3x

Step 2: Solve for x

Combine like terms:                    12 = 6 - 2xSubtract 6 on both sides:            6 = -2xDivide -2 on both sides:               -3 = xRewrite:                                         x = -3

Step 3: Check

Plug in x to verify it's a solution.

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