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

<em>Check: </em>

-⅗[15(-20) - 30] = 198

-⅗(-300 - 30) = 198

-⅗(-330) = 198

198 = 198
