Given:

• x+y = 4

• 2x+3y= 6.

To find :

• x and y.

Solution:

• x+ y = 4

=> x = 4 - y

put x in :

• 2x + 3y = 6

=> 2 (4-y)+3y = 6

=> 8 - 2y +3y = 6

=> y = 6 - 8

=> y = -2 .

Now, put y in x+y= 4.

=> x+(-2)= 4

=> x - 2 = 4

=> x = 4+2

=> x= 6.

Hence, the value of x is 6 and y is -2.

I hope it will help you.

Regards.
