2(x-6)=3(x+3)

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

2(x−6)=3(x+3)

Step 1: Simplify both sides of the equation.

2(x−6)=3(x+3)

Simplify: (Show steps)

2x−12=3x+9

Step 2: Subtract 3x from both sides.

2x−12−3x=3x+9−3x

−x−12=9

Step 3: Add 12 to both sides.

−x−12+12=9+12

−x=21

Step 4: Divide both sides by -1.

−x/−1=21/−1

x=−21

Answer:

x=−21
