WebFeb 10, 2024 · Divide both sides of the equation to "solve for x." Once you have the x term (or whichever variable you are using) on one side of the equation, divide both sides of the equation to get the variable alone. [3] For example: 4x = 8 - 2y. (4x)/4 = (8/4) - (2y/4) x = 2 - ½y. 3. Plug this back into the other equation. WebHere are the steps. 1. Turn on your graphing calculator. (It needs to be a TI-83 or better) 2. click 2nd, matrix. 3. click to the right until you are on the setting, EDIT. 4. select 1 of the matrices. It will bring up the matrix size on the top row and the matrix at the bottom. 5. change the matrix size to 3 x 4.
