9x + - 7x - 5 = - 20

Find the value of x

9x-7x-5=-20

Step 1: Simplify both sides of the equation.

9x-7x-5=-20

9x+-7x+-5=-20

(9x+-7x) + (-5) = -20 (Combine Like Terms)

2x+-5=-20

2x-5=-20

Step 2: Add 5 to both sides.

2x-5+5=-20+5

2x=-15

Step 3: Divide both sides by 2.

2x/2=-15/2

x=-15/2
