6x - 4y
7x + 8y
y = 14
if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7
7y = 3y - 12 4y = -12 y = -3
6x plus 4y
6x - 4y
.225
It's the equation of a straight line, with a slope of (6/7) and a y-intercept of (-12/7).
7x + 8y
y = 14
if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7
(5, 1)
7y = 3y - 12 4y = -12 y = -3

6x+7y=-6 3(-2x-3y=2) +________ -2y=0 => y=0 Therefore x=-1
