-7 + y = -19
-2x + 3y = -19

y = -12, x = -17/2 or -8

Step-by-step explanation:

-7 + y = -19 . . . . . . .. . eq1

-2x + 3y = -19  . . . . . . .eq 2

solve for y in eq 1

that is y = -19 + 7

          y = -12

substitute y into eq 2.

-2x + 3(-12) = -19

-2x - 36 = -19

-2x = -19 + 36

-2x = 17

x = -17/2 or -8

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )
