There are 5 ways to solve a system.
The most popular is to write both in standard notation then add the equations together. The easiest to explain is to use substitution. Solve one for one of the variables then substitute in the other equation.
The other ways to solve are to use graphing and find the intersection. Determinants and matrices are the other two ways.

How can variables be used to help solve a math problem?
If you don't know something in a math equation you can replace it with a variable and then solve it algebraically.
Solve this equation for A A divides 2 equals 4?
Written algebraically, the equation is (2/A)=4.The first step is to move the variable A from the denominator. To do this, multiply both sides of the equation by A:A*(2/A)=4*AThe A in the denominator on the left is canceled out and we are left with:2=4*ATo solve for A divide both sides of the equation by 4:2/4=ATwo over four simplifies to one half, which equals A:1/2=A
How do you find the volume of a cylinder with just the volume and the height?
No matter what you're finding, use the equation V=πr2h. Then solve algebraically. V=volume h=height r=radius πr2=area of the base
What do you call the solution of a equation derived from an original equation that is not a solution of the original equation?
That's an extraneous solution. You need to check for these when algebraically solving equations, especially when you take both sides of an equation to a power.
What are some ways to solve an equation?
