Answer: x = -8, y = 13

Step-by-step explanation:

x+y=5

3x+y=-11

now subtract the two equations

x-3x+y-y=5-(-11)

-2x=16, x = -8

now substitute

-8 + y = 5, y = 13

⚡Hello⚡

Solve

3{×+y=5

-1{3×+y=-11

3×+3y=15

-3×-y=-11

2y=4

y=4÷2

Y=2

×+y=5

×+(2)=5

×=5-2

×=3

•Verification•

×+y=5

(3)+(2)=5

3+2=5

5=5

Equality Holds✔️
