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

3x+6=x9

Step 1: Cross-multiply.

3x+6=x9

(3)*(9)=x*(x+6)

27=x2+6x

Step 2: Subtract x^2+6x from both sides.

27−(x2+6x)=x2+6x−(x2+6x)

−x2−6x+27=0

Step 3: Factor left side of equation.

(−x+3)(x+9)=0

Step 4: Set factors equal to 0.

−x+3=0 or x+9=0

x=3 or x=−9
