Algebra 2 – Solving Systems of Equations Using Inverse Matrices
Yay Math In Studio returns with a hand-holding lesson on solving systems of equations using inverse matrices. In a 2x2 matrix, we calculate the inverse, then use it to come up with the solution to the system. We learn how multiplying the original matrix by its inverse produces the "identity matrix." There are other videos on multiplying matrices, obtaining the determinant and calculating the inverse of a matrix, but we cover those skills again here. YAY MATH!
