-3x-y=-2

4x-4y=8

Thank you for the opportunity to help you with your question!

y = -1 and x = 1

wait i will send you the details

3x + y = 2

x - y = 2

so :

x = 2 + y

we put x on the first equation :

3(2 +y) + y = 2

6 + 3y + y = 2

4y = -4

so : y = -1

we have to put y on one equation :

x - ( -1) = 2

x + 1 = 2

x = 1

if you don't understand just ask

i am glad to work with you just invite me each time

GOod luck
