Step-by-step explanation:
5x + 2y = 17
3x - 2y = 7
Add the two equations to eliminate y
5x + 2y = 17
3x - 2y = 7
8x = 24
Divide each side by 8
8x/8 = 24/8
x =3
Now we need to find y
5x+2y = 17
5(3) +2y =17
15+2y =17
Subtract 15 from each side
15-15+2y =17-15
2y =2
Divide each side yby2
2y/2 =2/2
y=1
