Stacy and Travis are rock climbing. Stacy's rope is 4 feet shorter than 3 times the length of Travis' rope. Stacy's rope is 23 feet long. Write and solve an equation to find the length t of Travis' rope. **Weegy:** Stacy's rope = 23 = 3t - 4; add 4 to both sides to get 27 = 3t; divide both sides by 3 to get the answer t = 9. Travis' rope is 9 feet long. (More)

-8x + x + 15 = -7x + 12

-7x + 15 = -7x + 12

-7x + 7x = 12 - 15

0 = -3 which is a false statement.

There is no solution for the equation -8x + x + 15 = -7x + 12

-7x + 15 = -7x + 12

-7x + 7x = 12 - 15

0 = -3 which is a false statement.

There is no solution for the equation -8x + x + 15 = -7x + 12

3(3x - 1) + 2(3 - x) = 0

9x - 3 + 6 - 2x = 0

7x + 3 = 0

7x = -3

x = -3/7

9x - 3 + 6 - 2x = 0

7x + 3 = 0

7x = -3

x = -3/7
