Answer:

x = 5

Explanation:

20(20-x) = 300

20( -x + 20) = 300

-20x + 20 * 20 = 300

-20x = 300 - 400

x = -100 / -20

x = 5

Answer:

x=5

Explanation:

20(20-x) = 300

Divide each side by 20

20/20(20-x) = 300/20

20-x = 15

Subtract 20 from each side

20-x-20 = 15-20

-x = -5

Multiply each side by -1

x = 5
