Respuesta :
2x + 4y = 36
3x - 4y = -6
--------------add
5x = 30
x = 6
2x+4y=36
2(6)+4y=36
12 + 4y = 36
4y = 24
y = 6
answer
(6, 6) is a solution of equations
(4,7) is NOT a solution of equations
3x - 4y = -6
--------------add
5x = 30
x = 6
2x+4y=36
2(6)+4y=36

4y = 24
y = 6
answer
(6, 6) is a solution of equations
(4,7) is NOT a solution of equations
using (4,7)
2(4) +4(7) = 8 +28 =36 True
3(4) - 4(7) = 12 -28 =-16 False (-16 is not -6)
(4,7) is not a solution
