Question

Write three solutions for the equation 7x- 8y=13

Answer 1

 I have only two solution

First solution:

7x - 8y = 13

7x = 13 + 8y 

x = (13 + 8y)/ 7

Second solution:

7x - 8y = 13

8y = 13 + 7y

y = (13 + 7y)/8


I HOPE THIS HELP U :-)

Answer 2

1:::
7x - 8y = 13
7x = 13 + 8y 
x = (13 + 8y)/7

2:::
7x - 8y = 13
8y = 13 + 7y
y = (13 + 7y)/8
