-x plus 4y-3x equals:
-x + 4y - 3 = 0
-x -3 = -4y
-x = -4y + 3
-x/-1 = (-4y + 3)/-1
x = 4y + 3
-x + 4y - 3 = 0
4y - 3 = x
4y = x + 3
4y/4 = (x + 3)/4
y = x/4 + 3/4
That makes: (x, y) = 1
-x+(4y-3x)= -x+4y-3x= (-x-3x)+4y= (-4x)+4y= -4x+4y= 4(y-x)
Either one of those two answers would be correct.
If 40 plus x equals 25 then x is equal to -15.
If 5 x equals 9 plus 2x then x equals?
It is (-1, 3).
