6x+3y = -9 3y = -6x-9 y = -2x-3 Therefore the perpendicular slope is 1/2
2x-11
-2x plus 3y equals 1
(2,7)
2x plus 3y
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
2x-3y=13
How do you add 2x plus 3y equals 18 in 5x-y equals 11
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
Collect like terms: 2x + 3y + 3y - 5 - 6 2x + 6y - 11
4.34684352143
2x + 3y = 1 y = 1/3 - 2x/3
