Answer 1

Answer:

The value of X=2 and the value of Y=1

Step by Step Expansion:

We solve this problem using A Elimination Method:

7x+4y=18 X1

x+2y=4 X7

_______

7x+4y=18

7x+14y=28

- - -

________

0-10y=-10

y=-10

-----

-10

_________

y= 1

put the value of y in equation 2

x+2y=4

x+2(1)=4

x+2=4

x=4-2

x= 2
