Question 896029
{{{6r+7=13+7r}}} Start with the given equation.



{{{6r=13+7r-7}}} Subtract {{{7}}} from both sides.



{{{6r-7r=13-7}}} Subtract {{{7r}}} from both sides.



{{{-r=13-7}}} Combine like terms on the left side.



{{{-r=6}}} Combine like terms on the right side.



{{{r=(6)/(-1)}}} Divide both sides by {{{-1}}} to isolate {{{r}}}.



{{{r=-6}}} Reduce.

Answer:


So the solution is {{{r=-6}}}
