Answer:
y=2 and x=7
Step-by-step explanation:
x-2y=3 equation 1
2x+4=18 equation 2
first we will find the value of x by using equation 2
2x+4=18
subtracting 4 on both sides to find the value of x
2x+4-4=18-4
2x=14
dividing 2 on both sides
2x/2=14/2
x=7
putting the value of x in equation 1
(7)-2y=3
subtracting 7 on both sides
7-7-2y=3-7
-2y=-4
dividing -2 on both sides
y=2
i hope this will help you :)
