Question 857965
{{{7=c/5 -7}}} Start with the given equation.



{{{7=(-5)/5 -7}}} Replace ALL copies of 'c' with -5 (since we are told that {{{c = -5}}})



{{{7=-1-7}}} Divide {{{-5/5}}} to get {{{-1}}}



{{{7=-8}}} Subtract. 



The last equation is <font color="red">FALSE</font>. So the original equation is <font color="red">FALSE</font> when {{{c = -5}}}
