Question 150751


{{{-3(p-7)+5p=6p-7}}} Start with the given equation.



{{{-3p+21+5p=6p-7}}} Distribute.



{{{2p+21=6p-7}}} Combine like terms on the left side.



{{{2p=6p-7-21}}} Subtract {{{21}}} from both sides.



{{{2p-6p=-7-21}}} Subtract {{{6p}}} from both sides.



{{{-4p=-7-21}}} Combine like terms on the left side.



{{{-4p=-28}}} Combine like terms on the right side.



{{{p=(-28)/(-4)}}} Divide both sides by {{{-4}}} to isolate {{{p}}}.



{{{p=7}}} Reduce.
