Question 992056


{{{a(b-c)=-4d}}}


divide both sides by a:
{{{(a(b-c))/a=(-4d)/a}}}


{{{b - c =(-4d)/a}}}


subtract b from both sides to isolate -c variable:
{{{- c =((-4d)/a) - b}}}


since you are solving for c, multiply by -1 to eliminate the negative:
{{{- c =((-4d)/a) - b}}}


{{{c =(4d)/a + b}}}
