Solve for x and y x-2y=3 2x+4=18

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
