Answer:
x=2 and y=-2
Step-by-step explanation:
y+3x= 4.......(1)
y-4x= -10.......(2)
Subtract equation 2 from 1
y+3x= 4
-y-4x= -10
------------
0+7x = 14
7x = 14
divide both sides by 7
7x = 14
---- ----
7 7
x = 2
Substitute x=2 into equation 1
y = -3x + 4
y = -3(2) + 4
y = -6 + 4
y = -2
x = 2 and y = -2
