What is the answer and work for these attached below
GrogVix [38]
-4(-5-b)=1/3(b+16) Multiply both sides by 3 to get rid of the fraction
-12(-5-b)=b+16  distribute the -12 to get rid of the parenthesis 
60+12b=b+16  get the b on the left side and non b values to the right side
11b=-44 solve for b
b=-44/11 simplify the fraction
b=-4

3/5(t+18)=-3(2-t)   multiply both sides by 5/3 to get rid of thefraction
t+18=-5(2-t)   distribute the -5 to get rid of the parenthises
t+18=-10+5t  get the t to the left side and non t values to the right
-4t=-28  solve for t
t=7
