Question

in solving the equation for x to distribute a minus 4 on one side of the equation what needs to be done on the other side of the equation

Answer 1

The distributive property is a simplification rule that does not change the value of an expression. Nothing need be done to the other side of the equation.

q = -4(3+x)
q = -4*3 -4*x . . . . . the -4 is distributed. The right side has not changed value.

Answer 2

Q = -4(3+x)
q = -4*3 -4*x 
q = -12-4x

Hope this helps!
