How to use rref to solve systems of equations

Web2 mrt. 2024 · If one of the equations looks more complicated than the other, just plug it into the easier equation. Plug x = 3 into the equation x - 6y = 4 to solve for y. 3 - 6y = 4. -6y = 1. Divide -6y and 1 by -6 to get y = -1/6. You have solved the system of equations by addition. (x, y) = (3, -1/6) 5. Check your answer. WebTo get the matrix in the correct form, we can 1) swap rows, 2) multiply rows by a non-zero constant, or 3) replace a row with the product of another row times a constant added to …
