Answer:
x=45/6
Explanation:
2+7y=8. 7y=8-2. 7y=6
7=7. y=6\7
insert the value of y in the second equation. 5x-7y=16
5x-7(6/7)=16
5x-49\6=16
collect the liketerms together
5x=16+49/6
5x=145/6(divide both sides by 5)
x=29/6
x=45/6
further.
confirm if the 2 in the second equation has an X coz the questions are normally set with both equations having both values x and y
