-7x - 17 = -9x + 13
Add 9x to each side: 2x - 17 = 13
Add 17 to each side: 2x = 30
Divide each side by 2 : *** x = 15 ***
To solve − 7 x − 17 = − 9 x + 13 , we first add 9 x to both sides, resulting in 2 x − 17 = 13 . After adding 17 and dividing by 2 , we find that x = 15 . This solution can be verified by substituting 15 back into the original equation and confirming both sides are equal.
