5x - 7y = 16 2 + 7y = 8.

what is x?

x=45/6

Step-by-step 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
