See explanation.

First yo ushould add #7# to both sides to leave the unknown on left side:

#-4x=24#

The last step is to divide both sides by the coefficient of #x#:

#x=24/-4#

#x=-6#

To check the solution you can substitute the calculated value to the original equation:

#-4*(-6)-7=24-7=17#

Left and right sides are the same, so the answer is correct.
