Answer:

the value of x is -1 and y is 10

Step-by-step explanation:

2y-4x=24

y+3x=7

subtracting both equations you get

y - 7x = 17

y = 17 + 7x

substitute it in any equation

y+3x=7

17+7x+3x =7

17 +10x=7

10x=7-17

10x=-10

x=-1

substitute x value in equation

2y-4x=24

2y-(-4)=24

2y+4=24

2y=20

y=10
