Question

1. What is the solution of
the pair of equations 5x-7y=7
and x+2y=3​

Answer 1

Step-by-step explanation:

taking x equal for both equations

x = (7 + 7y)/5

x = 3 - 2y

7 + 7y = 5(3 - 2y)

7 + 7y = 15 - 10y

17y = 8

y = 8/17

put the value of y in any of the equation

x = 3 - 2(8/17)

x = 3 - 16/17

x = (51 - 16)/17

x = 35/17
