Question 615507
{{{3b-2=7b+4}}} Start with the given equation.



{{{3b=7b+4+2}}} Add {{{2}}} to both sides.



{{{3b-7b=4+2}}} Subtract {{{7b}}} from both sides.



{{{-4b=4+2}}} Combine like terms on the left side.



{{{-4b=6}}} Combine like terms on the right side.



{{{b=(6)/(-4)}}} Divide both sides by {{{-4}}} to isolate {{{b}}}.



{{{b=-3/2}}} Reduce.
