The answer to the math problem of 18 minus 4x equals negative 2 is x equals 5.
To justify something in math is to prove it. Example: Justify 4x = 8 when x = 2. When x = 2, 4(2) = 8. Done. By doing this I justified that 4x = 8 when x = 2.
x2-4x-12 = (x-6)(x+2) when factored
x= 1.5 4x -2=4 <<< Original problem +2 +2 <<< reverse operations (problem requires subtraction, so add to solve) 4x=6 <<< New problem 4x/4=6/4 <<<reverse operations (new problem requires multiplication, so divide to solve) x=1.5 <<< answer
Watch me as I do it. Perhaps you can pick up some pointers.-34 = 2 + 4xSubtract 2 from each side of the equation:-36 = 4xDivide each side by 4 :-9 = x

If you mean 3x2+4x-2 = 0 then it can be solved by means of the quadratic equation formulla
x2-4x-12 = (x-6)(x+2) when factored
x= 1.5 4x -2=4 <<< Original problem +2 +2 <<< reverse operations (problem requires subtraction, so add to solve) 4x=6 <<< New problem 4x/4=6/4 <<<reverse operations (new problem requires multiplication, so divide to solve) x=1.5 <<< answer
2+2=?
4x
4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2

The equation 5X plus 4X-2-2 times2 X-1 plus 3 X plus 2 equals 2. This is a math problem.
The teacher posed the math problem 5 plus 11 and 1/2. I had a problem figuring out the math problem.
4X^2 - 8X factor out 4X 4X(X - 2)
