Only one step. Divide both sides of the equation by -4 to get
-4x/(-4) = 28/(-4) so that
x = -7

1) -4x=28 =problem
2) -4x=28 divide by negative four on both sides
---------- So -4x divided by -4 is x and 28 divided by -4 is -7
-4 -4
3) X= -7 Therefore X equals -7

First.: pass the -4 to the other side of the equation, and it should be doing an inverse operation. In this case it will be dividin. So you will get: X=28/-4. Then solve the division it will be -7. So , X= -7.

divide 28 by -4
x = -7

-4x = 28
Multiply both sides by 1/4 (or divide by 4. Same thing):
-4x * (1/4) = 28 * (1/4)
-x = 7
Multiply both sides by -1 to make x positive:
-x * (-1) = 7 * (-1)
x = - 7
That's your answer.

-4x = 28
divide both sides by -4 to get x all by itself
x = -7
plug x back into the equation to check

First, Divide each side by -4
-4X=28
X= - 7
That's all there is to it.
Remember, to undo things, do the opposite. Or multiply by the reciprocal. So divide by - 4 or multiply by -1/4

First you divide both sides by -4. This leaves you with x = -7. Therefore -7 is your answer.
