Answer:
-6 and 7
Step-by-step explanation:
x is one number and y is the other
(1)----------------- 8x+5y=-13
(2)------------------ x+y= 1
first, let multiply both sides of (x+y=-1) by 8
(3)----------------- 8x+8y=8
lets subtract (1) from (3)
(8x+8y)-(8x+5y)=8-(-13)=3y
8-(-13)=3y -> 21=3y
y=7
lets plug in 7 into (2) for x
x+7=1
x=-6
the numbers are -6 and 7
