remember you can do anything to an equation as long as you do it to both sides 8-(3+b)=b-9 remember the distributive property a(b+c)=ab+ac distribute that invisible -1 -(3+b)=-1(3+b)=-1(3)-1(b)=-3-b 8-3-b=b-9 add like terms 5-b=b-9 add b to both sides 5=2b-9 add 9 to both sides 14=2b divide both sides by 2 7=b b=7
