Answer:
13 (x= -2, y= 1)
14 (x=3, y= -4)
Explanation:
1 x+5y=3
3x-2y=-8
u gonna add 3 into x and make it negative
2 -3x-15y=-9
3x-2y=-8
x will be gone since 3x-3x
3 -17y=-17
y= 1
going to add y into x+5y=3
x+5=3
x=-2
question 14
y=2x-10
y=-4x+8
add - to everything in the bottom
y=2x-10
-y=4x-8
0=6x-18
18=6x
3=x
add 3 into x in y=2x-10
y=6-10
y=-4
