Answer: 1 [tex]\frac{1}{7}[/tex]

Please read the whole thing and make sure you understand. Trust me, only copying and not learning will only make math harder.

Step-by-step explanation:

2x + 3 = 9x - 5

Add 5 to both sides, cancelling off the 5 on the right

2x + 3 + 5 = 9x

2x + 8 = 9x

Subtract 2x from both sides, cancelling off the 2x on the left

8 = 9x - 2x

8 = 7x

Divide each side by 7, cancelling of the 7 from the x on the right

8 / 7 = x

1.4285714286... = 7
