Putting in the given equation we get,
So, 4m + 3y = 14 => 4m + 3y – 14 = 0 ……………..…..(1)
3m – 4y = 23 => 3m – 4y – 23 = 0 ……………………….(2)
By cross-multiplication, we get,
m/(-69-56) = y/(-42-(-92)) = 1/(-16-9)
-m/125 = y/50 = -1/ 25
-m/125 = -1/25 and y/50 = -1/25
m = 5 and b = -2
m = 1/x = 5
So , x = 1/5
y = -2
