-6x/-6=18/-6 x=-3
If: 6x-6 = 4x Then: x = 3
It equals -36. To solve replace x with -6, because it is the value given in the problem and then just multiply. 6(-6)= -36.

6x-y=-14 2x-3y=6
6x + 2 = 6 6x = 4 x = 2/3
6x+13 = 97-6 6x = 97-6-13 6x = 78 x = 13
-6x
-6x = 6y + 6 -6x = 3y - 12 Subtracting the second from the first gives: -6x - -6x = 6y - 3y + 6 - -12 → 0 = 3y + 18 → 3y = -18 → y = -6 Substituting in the first: -6x = 6y + 6 → -6x = 6(-6) + 6 → -6x = -36 + 6 → -6x = -30 → x = 5 Thus x = 5, y = -3 solve the simultaneous equations.
6x - 3y = 6 y= 2x + 5 replace 2x + 5 for y into the first equation 6x - 3y = 6 6x - 3(2x + 5) = 6 6x - 6x - 15 = 6 0 - 15 = 6 -15 = 6 False So the system has no solution.
6x
If you mean: 6x-5 = 31 then x = 6
