Solve by method of elimination:
2x +3y =10 Equation A
-3x+y =18 Equation B
Step 1. Multiply Equation B by 3 and subtract from Equation A to eliminate y terms
Step 2. Divide by 11 to both sides of the equation
Step 3. Substitute in Equation A to find y
Step 4. Add 8 to both sides of the equation to find y
Step 5. Divide by 3 to both sides of the equation
Step 6. Check solution of and with Equation B
which is a true statement.
Step 7. ANSWER: The solution is (-4,6) or x=-4 and y=6 for the linear system of equations.
I hope the above steps and explanation were helpful.
