Step-by-step explanation:

Answer 2

Answer:

x = -20  

Step-by-step explanation:

-⅗(15x - 30) = 198

Multiply each side by 5

-3(15x - 30) = 990

Distribute the -3

-45x + 90 = 990

Subtract 90 from each side

-45x = 900

Divide each side by -45

x = -20

Check:

-⅗[15(-20) - 30] = 198

  -⅗(-300 - 30) = 198

          -⅗(-330) = 198

                 198 = 198
