Question

Solve –3(2 – 5w) = 9w + 66 for w.

Answer 1

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

−3(2−5w)=9w+66

Step 1: Simplify both sides of the equation.

−3(2−5w)=9w+66

(−3)(2)+(−3)(−5w)=9w+66(Distribute)

−6+15w=9w+66

15w−6=9w+66

Step 2: Subtract 9w from both sides.

15w−6−9w=9w+66−9w

6w−6=66

Step 3: Add 6 to both sides.

6w−6+6=66+6

6w=72

Step 4: Divide both sides by 6.

   6w

    6

=    72

     6

w=12

Answer:

w=12
