Question 945268
solve each equation show all your steps and write a justification for each step. I'm working on algebraic proofs. 
1) 1/5(a+10)=-3 I tried I don't know if it's right 
a+2=-15  **** You divided the 10 by 5, but not a.
-----
subtract 2
a=17 ?
================
1/5(a+10)=-3
Multiply by 5 to eliminate fractions.
(a+10) = -15
Subtract 10
a = -25
