5x+y=2 y=2-5x
5y=x+9
5(2-5x)=x+9
10-25x=x-9
-24x=-1
x=-1/24
------------------
5(-1/24)+y=2
-5/24+y=2
y=2+5/24
y=53/24
-----------------
5(-1/24)+53/24=2

solve system using substution method
5x+y=2
5y=x+9
solution ?/26,47/?
5x + y = 2 ------- eq(i)------> y = -5x + 2
5y = x + 9 ------- eq(ii)
Substitute -5x + 2 for y on eq (ii)
5(-5x + 2) = x + 9
-25x + 10 = x + 9
-26x = - 1
Substitute for x in eq (ii), 5y=x+9
130y = 1 + 234 ----> Multiplying by LCD, 26
130y = 235
=
