How to solve for systems of equations
WebMar 26, 2016 · When a system of equations is simple, the easiest way to solve it is by substitution. For example: x + 3 = y. 3 x + y = 7. The first equation tells you that the value of y in terms of x is x + 3. To solve this system, substitute x + 3 for y in the second equation: Now, this equation has only one variable, so you can solve it: WebA set of Google Slides teaching how to solve a system of linear equations with substitution, including no solution and infinite solutions. Assumes that students have already seen solving systems by graphing and that students can solve an equation for x or for y. Includes Pear Deck slides to make lesson interactive.
