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
