Hello! What type of work is that so I can specifically know! :)

Answer 2

The value of x and y is -2 and 3

step by step explaination:

7x + 3y = -5 be equation 1st and x + y =5 be equation 2nd and multiply equation 2nd by 3 then subtract it .

then we get,

7x + 3y = -5

3x + 3 y= 3

(-). (-). (-)

_________

4x. = -8

x =. - 8/4

x = -2

substitute the value of x in equation in 1

7x +3y = -5

7* (-2) + 3y = -5

-14 + 3y = -5

3y = 14-5

y =9/3

y=3
