Question

What is -6(3r-8)=138

Answer 1

Answer: r=−5

Explanation:

−6(3r−8)=138

(−6)(3r)+(−6)(−8)=138(Distribute)

−18r+48=138

Step 2: Subtract 48 from both sides.

−18r+48−48=138−48

−18r=90

Step 3: Divide both sides by -18.

−18r /−18 = 90 /−18 r= −5

Answer 2

So 3-8 is -5 and the -6x -5 is -30r so r is 128
