Question

3x - 9(x-2) = 18x + 30

Answer 1

Answer: x= −1/2

Step-by-step explanation:

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

3x−9(x−2)=18x+30

Step 1: Simplify both sides of the equation.

3x−9(x−2)=18x+30

3x+(−9)(x)+(−9)(−2)=18x+30(Distribute)

3x+−9x+18=18x+30

(3x+−9x)+(18)=18x+30(Combine Like Terms)

−6x+18=18x+30

−6x+18=18x+30

Step 2: Subtract 18x from both sides.

−6x+18−18x=18x+30−18x

−24x+18=30

Step 3: Subtract 18 from both sides.

−24x+18−18=30−18

−24x=12

Step 4: Divide both sides by -24.

−24x

−24
