Solve by substitution linear equations
WebFeb 16, 2024 Β· So, the steps for using the substitution method to solve a system of linear equations are: Rewrite one of the equations to isolate one variable. In the other equation, substitute the value of your isolated variable in for that variable. Solve this second equation for the other variable. You should have a numerical value. WebOct 10, 2024 Β· Take that value of x, and substitute it into the first equation given above (x + y = 3). With that substitution the first equation becomes (1+y) + y = 3. That means 1 + 2y = 3. Subtract 1 from each side: 2y = 2. So y = 1. Substitute that value of y into either of the two original equations, and you'll get x = 2.
