Question 540999
{{{-7(2b-4)=5(-2b+6)}}} Start with the given equation.



{{{-14b+28=-10b+30}}} Distribute.



{{{-14b=-10b+30-28}}} Subtract {{{28}}} from both sides.



{{{-14b+10b=30-28}}} Add {{{10b}}} to both sides.



{{{-4b=30-28}}} Combine like terms on the left side.



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



{{{b=(2)/(-4)}}} Divide both sides by {{{-4}}} to isolate {{{b}}}.



{{{b=-1/2}}} Reduce.

Answer:


So the solution is {{{b=-1/2}}}
