Solving a System of equations by elimination step by step

" Line one" or "equation 1"
" Line two" or "equation 2"
Step 1: Multiply L1 by -1 (Line 1)
Step 2: Recopy "new" L2, with L1
underneath it.
Step 3: Add the equations together to
eliminate the x
Step 4: Solve for y
Step 5: Use L1 to substitute y with 6
Step 6: Solve for x
Step 7: Substitute your point into both L1
and L2 to check your answer of (5,6)
