Cramer’s Rule is a method that uses determinants to solve systems of equations that have the same number of equations as variables. Consider a system of two linear equations in two variables. a1x + b1y = c1 a2x + b2y = c2. The solution using Cramer’s Rule is given as.
WebStep 2: Setting Up Your Matrix. After you find or create a system of equations you want to solve you will need to rearrange the equations so that they are in the form x+y+z = constant (see image). Once your equations are in this form, you will need to rewrite them in matrix form. Each row of the matrix represents x, y, z, and constant respectively. WebMar 2, 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.
