x=1, y=1
x+7x+3y-y =8x+2y =2(4x+y)
8x+2y=4x=-y/4+0.5y=-4x+2
x=7 and y=4
x=4, y=9 (4,9)
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
x=1, y=1
10x - 5y + 2x - 3y = 12x - 8y
It simplifies to: 12x+3y
x+7x+3y-y =8x+2y =2(4x+y)
8x+2y=4x=-y/4+0.5y=-4x+2
x=7 and y=4
x=4, y=9 (4,9)
no its not a solution
-4
These are equations of two straight lines. Provided the equations are not of the same or parallel lines, there can be only one ordered pair. So the ordered pair is - not are : (0.5, -1)
3y + 18 = -8x + 3Subtract 18 from each side:3y = -8x - 15Divide each side by 3:y = (-8/3)x - 5
