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.
