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)
-4
no its not a solution
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
