Answer:
(-4, 5)
Step-by-step explanation:
12x + 14y = 22
12x - 3y = -63
Rewrite the first equation. Multiply both sides of the second equation by -1 and write it below the first equation. Then, add the equations.
12x + 14y = 22
(+) -12x + 3y = 63
---------------------------
17y = 85
17y/17 = 85/17
y = 5
Substitute y with 5 in the first original equation and solve for x.
12x + 14y = 22
12x + 14(5) = 22
12x + 70 = 22
12x = -48
x = -4

No because They lose 12 sand that puts them at -12. Then they gain 5 which puts them at -7 and then they lose 8 which puts them at -15. Please mark as brainliest
