Question

I need to find the basic of finding x and solving the problem ?????

Answer 1

x=-8

Explanation:

9x+1-7x-5=-20

2x-4=-20

2x=-20+4

2x=-16

x=-16/2

x=-8

Answer 2

x = -8

Explanation:

So, the equation is 9x + 1 - 7x -5 = -20:

Step 1: Add 5 to both sides of the equation to cancel out the -5; The new equation is 9x + 1 - 7x = -15.

Step 2: Now subtract 1 from both sides of the equation to cancel out the +1; The new equation is 9x - 7x = -16.

Step 3: Subtract 9x and 7x as they have like terms; The new equation is

2x = -16.

Step 4: Divide 2 on both sides to isolate x, and the answer is x = -8.
