How to solve for y in ax+by=c?

While the system of linear equations has infinitely many solutions there are several ways to find the one that satisfies the system of equations. One is the Gauss-Jordan method, which is especially well-suited when there are many variables. The Gauss-Jordan method consists of three steps: first, find all solutions to the system of equations for the given variables; second, find the solutions that are linear combinations of these original solutions; and third, eliminate any solutions that are multiples

How to solve for y in linear equation with variables?

If you are solving for y, the first thing to do is isolate it. In other words, if it appears on both sides of the equation, subtract the other variable from both sides. For example, if you have the equation 6x+5y=20, you would first subtract 5 from both sides to get 6x+y=20. Then, you would solve for y.

How to solve quadratic equations with variables?

The quadratic equation is one of the most commonly used forms of an algebraic equation because it allows us to solve for the solutions of a variety of different equations. In high school or college algebra, you may have come across the quadratic equation ax2+bx+c=0. The variables in this equation are a, b, and c. You can factor the left side of the equation to find the solutions for the roots. The roots of the equation are the values of

How to solve for y in quadratic equation with variables?

Quadratic equations with variables are those containing two variables (and no exponents or radicals) and two coefficients. The two solutions to the equation can be written as where and are the solutions for the two variables.

How to solve for y in quadratic equation with variables without calculator?

One of the easiest ways to solve for y is to use your calculator and do the quick solve method. If you are dealing with two variables, you can use the quadratic formula. However, if you are solving a more complex equation, this method can be rather tedious. Instead, you can use the Pythagorean method to solve for the unknown variable.
