IXL Algebra1 - U.14 Solve a System of Equations Using Any Method

We are given systems of linear equations in various forms, they start with substitution set-ups where the x or y value is given and we substitute to find the other variable. Then a system of y=mx+b where we can substitute for the y in either case and solve the equation with x's on both sides.

Finally, we are given two equations in standard form and use addition (with "row" operations to solve them.
