Solve the equation. (5x+7)(8x-9)=0
Lina20 [59]

Answer:

x = -7/5 and x = 9/8

Step-by-step explanation:

To solve this equation, set both parts of the "expression" equal to 0.

5x + 7 = 0

Subtract 7 from both sides.

5x = -7

Divide both sides by 5.

x = -7/5

8x - 9 = 0

Add 9 to both sides.

8x = 9

Divide both sides by 8.

x = 9/8
