Question 945268: my homework says to 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
subtract 2
a=17 ?

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.

a=17 ?
================
1/5(a+10)=-3
Multiply by 5 to eliminate fractions.
(a+10) = -15
Subtract 10
a = -25
