The problem. Here is the problem: negative 5x plus 12 equals 6x minus 12. A linear equation in x: isolate x using inverse operations.
Step by step. Start with the equation. Subtract 6x from both sides. Subtract 12 from both sides. Divide both sides by negative 11.
The answer. So the answer is x equals 24 over 11 approximately 2.1818182. Doing the same operation to both sides keeps the equation balanced. Undoing addition, then multiplication, leaves x alone.
Check. x equals 2.1818182: left side equals 1.0909091, right side equals 1.0909091, which checks out.
