Solve by Substitution or Elimination: 2j-3k=3 with the problem just underneith the one above. j+k =14

Step 1. We form a System of Equations

Step 2. The following steps solve the system of equations by substitution:

Solved by pluggable solver: SOLVE linear system by SUBSTITUTION

Solve:
We'll use substitution. After moving -3*k to the right, we get:
, or . Substitute that
into another equation:
and simplify: So, we know that k=5. Since , j=9.

Answer: .

I hope the above steps are helpful, Leona.

And good luck in your studies!
