Answer:
3 . . . goes in both boxes
Step-by-step explanation:
Use the distributive property. Remove the common factor to outside parentheses:
3(m +n) = a multiple of 3
8x-10y=-23
9x+10y=-16
(8x+9x)+(10y-10y)=(-23+(-16))
17x+0y=-39
x=-39/17
8(-39/17)-10y=-23
-312/17-10y=-23
-10y=-23+312/17
-10y=-79/17
y=79/170
