Question 113915


{{{c+20=55-4c}}} Start with the given equation




{{{c=55-4c-20}}}Subtract 20 from both sides



{{{c+4c=55-20}}} Add 4c to both sides



{{{5c=55-20}}} Combine like terms on the left side



{{{5c=35}}} Combine like terms on the right side



{{{c=(35)/(5)}}} Divide both sides by 5 to isolate c




{{{c=7}}} Divide
