Respuesta :
(x,y) = (-7, 1)
let me know if this helps, or you need the steps
check your work
1 = 3(-7) + 22
1 = -21 + 22
1=1
1 = 2 (-7) +15
1 = -14 + 15
1=1
We subtract the 2 equations which eliminates the y:-
3x - 2x + 22 - 15 = 0
x + 7 = 0
x = -7
Now plug x = -1 into the first equation:-
y = 3(-7) + 22 = 1
Answer is (-7, 1)
