25) write a system of equations with the solution (4, −3). Once your equations are in this form, you will need to rewrite them in matrix form. Substituting into the first equation:

The Solution Is When These Three Planes Cross A Single Point.

If the three equations in such a linear system are “independent of one another,” the system will have either one solution or no solutions. We may need to rewrite one or both equations! Create a matrix that contains the coefficients of the variables in your system of equations.

The Calculator Will Use The Gaussian Elimination Or Cramer's Rule To Generate A Step By Step Explanation.

Substitute the obtained value in any of the equations to also get the value of the other variable. Solve the systems of equations below. Systems of equations are sets of equations where the solution is the intersecting point(s) between the equations.
