its 10x +9y +1z
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
10x - 3y + 2x - 4y =(10x + 2x) + (-3y - 4y) =12x - 7y
(4, -7)
x/5y + 2x/3y = 3x/15y + 10x/15y = 13x/15y
its 10x +9y +1z
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
10x - 3y + 2x - 4y =(10x + 2x) + (-3y - 4y) =12x - 7y
(4, -7)
10x+2x-3y-4y=12x-7y
x/5y + 2x/3y = 3x/15y + 10x/15y = 13x/15y
2x+3y=13 3x-y=3 x=2
If you mean 3y+24 = y-12 then the value of y works out as -18
