6. Solve the the following system of equations: 4y+2x=14 2y+2x=10
Inessa05 [86]
4y+2x=14 ==> multiply this 1st equation by (-1) => -4y-2x=-14
Now add it up to the 2nd equation
-4y-2x=-14
 2y+2x=10
--------------    And now add them up
-2y +0x=-4
==> -2y=-4==> 2y = 4 &    y=2                   
Last step: plug y into any equation & you will find x=3

RT = 14 + 9

RT = 23
