Solve the system by elimination.
 2x  3 y  6

2 x  2 y  14
Objective
The student will be able to:
solve systems of equations
using elimination
Solving a system of equations by elimination
using multiplication.
Step 1: Put the equations in
Standard Form.
Standard Form: Ax + By = C
Step 2: Determine which
variable to eliminate.
Look for variables that have the
same coefficient.
Step 3: Multiply the
equations and solve.
Solve for the variable.
Step 4: Plug back in to find
the other variable.
Step 5: Check your
solution.
Substitute the value of the variable
into the equation.
Substitute your ordered pair into
BOTH equations.
What is the first step when solving with
elimination?
