-7%282b-4%29=5%28-2b%2B6%29 Start with the given equation.


-14b%2B28=-10b%2B30 Distribute.


-14b=-10b%2B30-28 Subtract 28 from both sides.


-14b%2B10b=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=%282%29%2F%28-4%29 Divide both sides by -4 to isolate b.


b=-1%2F2 Reduce.
