-8x -7y
3y + 18 = -8x + 3Subtract 18 from each side:3y = -8x - 15Divide each side by 3:y = (-8/3)x - 5
(1, 1)
7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387
x+7x+3y-y =8x+2y =2(4x+y)
8x + 3y = 248x - 8x + 3y = -8x + 243y = - 8x + 243y/3 = (- 8x + 24)/3y = -8x/3 + 24/3y = (-8/3)x + 8 this is the slope-intercept form of the equation of the line, y = mx + b, where the slope m is -8/3 and the y-intercept b is 8.
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
-8x+3y=12 3y = 8x+12 y = (8/3)x + 4 So it will be a line with slope 8/3 and y intercept of 4

8x-3y=6-4x gives 12x-3y=6 which in standard form is y=-2+4x
3y + 18 = -8x + 3Subtract 18 from each side:3y = -8x - 15Divide each side by 3:y = (-8/3)x - 5
8 + 4 + 9y + 10 - 8x + 12xy - 3y = 0 12 + 10 + 9y - 8x + 12xy - 3y = 0 22 + 9y - 8x + 12xy - 3y = 0 9y - 3y - 8x + 12xy = -22 6y - 8x + 12xy = -22 6y + 12xy = 8x - 22 y(12x + 6) = 8x - 22 y(12x + 6)/12x + 6 = (8x - 22)/(12 + 6) y = 2((2^3 * x)/(12x + 6) - 22/(12x + 6) y = 2(2^2 * x - 11)/(12x + 6) y = 2(4x - 11)/2^2 * 3(2^1 * x + 1) y = 4x - 11/6(2 * x + 1) y = (4x - 11)/3(2x + 1) 8 + 4 + 10 - 8x + 9y + 12xy - 3y = 0 22 - 8x + 9y -3y + 12xy = 0 22 - 8x + 6y + 12xy = 0 x = -(6y + 22)/2(3y - 2) x = -(3y + 11)/2(3y - 2)

16x2 + 8x + 1 - 9y2 = (4x + 1)2 - (3y)2 which is a difference of two squares. = (4x + 1 + 3y)*(4x + 1 - 3y)
7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387
10x - 5y + 2x - 3y = 12x - 8y
