8 0

Answer:

x = 8

Step-by-step explanation:

Step 1: Simplify both sides.

7 - 3x = -2/5x - 69/5

7 + - 3x = -2/5x + -69/5

-3x + 7 = -2/5x + -69/5

Step 2: Add 2/5x to both sides.

-3x + 7 + 2/5x = -2/5x + -69/5 + 2/5x

-13/5x + 7 = -69/5

Step 3: Subtract 7 from both sides.

-13/5x + 7 - 7 = -69/5 - 7

-13/5x = -104/5

Step 4: Multiply both sides by 5/(-13)

(5/-13) * (-13/5x) = (5/-13) * (-104/5)

x=8
