………………………………………………………………………………………………… (1)
…………………………………………………………………………………………………… (2)
Using elimination method, since the coefficient of Y in both equations is 7 we subtract equation (2) from (1)
–
-14
Dividing both sides by 7
Substituting the for X in equation (1) to find the value of Y
But
Dividing both sides by 7
Therefore: and
