Question 693656
x-2y=1 can be rewritten as x = 2y + 1
and substituted into 6x-5y=20 as
6(2y+1) - 5y = 20 ==> distribute the 6
12y + 6 - 5y = 20
7y + 6 = 20
7y = 20 - 6
7y = 14
y = 2
...
Plug in the y value into either equation and solve for x
x = 2(2) + 1 = 4 + 1 = 5
x = 5
...
({{{highlight_green(5)}}},{{{highlight_green(2)}}}) is the solution/point of intersection
