Question 691201
multiply either equation by -1 and add them
x+6y=79
-1(x-4y=-41) ==> -x + 4y = 41
x + - x + 6y + 4y = 79 + 41
10y = 120
{{{highlight_green(y = 12)}}}
...
Multiply the first equation by 2 and the second by 3, then add
2(x+6y=79) ==> 2x + 12y = 158
3(x-4y=-41) ==> 3x - 12y = -123
2x + 3x + 12y + -12y = 158 + -123
5x = 35
{{{highlight_green(x=7)}}}
