9y - 4x
Y-8x plus 9y equals 10y-8x.
9y+3 = 5y+13 9y-5y = 13-3 4y = 10 y =2.5
12x-4y+9z+2y =12x-2y+9z
5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■
It is 12x + 11y + 9.
It can be simplified to: 12x-3w+13y
Without an equality sign it is not a straight line equation but if you mean 9y-12x-72 = 0 then y = 4/3x+8
12x - 9y = 6, 12x + 20y = 64 29y = 58 y = 2 x = 2
It can be simplified to: 9y-2x
We have 3x+9y=36, or equivalently 12x+36y=144. We also have 12x+4y=18, so subtracting these we have 32y=126 or y=63/16. Substituting this into our original equation leaves 3x=36-9*63/16 or x = 12-3*63/16 = 3/16. So: x=3/16, y=63/16
1: 12x - 9y = 6 2: 12x + 20y = 64 Subtract 1 from 2: 29y = 58 y = 2. So does x.
12x + 5 - 2x =(12x - 2x) + 5 =10x + 5 =5 (2x + 1)
9y - 4x
(-y+4)+ (9y-6) (9y-y) + (4-6) 8y - 2
The variables have no known values and as an expression it is: 5x+9y+5
Y-8x plus 9y equals 10y-8x.
