6x + 5y = 3 4x + 3y = 3 x + y = 14 3x 2y = -19 – Step 1: Eliminate by adding the two or subtracting equations. *Add if the signs are opposite, subtract if the signs are the same. Step 2: Solve for the first variable by solving the equation Step3: Substitute your solution from step 2 into one of the original equations (you may choose either one to use). for the second Step 4: Solve variable by solving the equation State the final answer as a (x , y) (x , y) coordinate (x, y) (___, ___) (___, ___) You can check your work by completing a LS/RS check. Substitute your (x,y) solution into the original equation that you DID NOT use in step 3 above.
