Answer:
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
