6x + 5 = 95 - 3x The main goal is to get "x" by itself. So you can first subtract 5 from both sides because whatever you do on one side of the equation, you do to the other side. 6x = 90 - 3x Next add 3x on both sides. 9x = 90 Last divide by 9 on both sides. x = 10
-6x^2 - 78x - 252 Improved answer: -6x+6x+7 When simplified = 7
There is no possible value of 'x' for which (6x-2) can be equal to (6x-12).
-6x-4-8 = -6x -12
8x - 2x = 90 so 6x = 90 so x = 15

1+6x+6x+8 1+ 12x +8 12x + 9 = 21 + x
When you have an expression like 6x - 6x, you can simplify it by combining like terms. In this case, the two terms are identical, so when you subtract one from the other, you are left with 0. Therefore, the result of 6x - 6x is 0.
6x - 9 = 21 6x = 21 + 9 6x = 28 x = 28/6 Reduce to: x = 14/3
There is no possible value of 'x' for which (6x-2) can be equal to (6x-12).
