The following steps solves the linear system using Substitition

Solved by pluggable solver: SOLVE linear system by SUBSTITUTION

Solve:
We'll use substitution. After moving 2*b to the right, we get:
, or . Substitute that
into another equation:
and simplify: So, we know that b=2. Since , a=1.

Answer: .
