Answer 2

Resposta:

Let's solve your equation step-by-step.

2x+21−6=−12+x−7

Step 1: Simplify both sides of the equation.

2x+21−6=−12+x−7

2x+21+−6=−12+x+−7

(2x)+(21+−6)=(x)+(−12+−7)(Combine Like Terms)

2x+15=x+−19

2x+15=x−19

Step 2: Subtract x from both sides.

2x+15−x=x−19−x

x+15=−19

Step 3: Subtract 15 from both sides.

x+15−15=−19−15

Answer:

x=−34
