3+6x = 4x+9 6x-4x = 9-3 2x = 6 x = 3
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
x=3
4x + 3y=9 x=0 y=3
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
x = -1/3
2x-3=4x+9 -2x-12=0 2x=-12 x=-6
5x = 4x + 9 x = 9
4x+9=2x-6 2x=-15 x=-7.5 x equals -7.5.
4x+5 = -9 4x = -9-5 4x = -14 x = -3.5
-4x + 3y = 9
4x
