Since these lines cross at the point (-1,-5), this is a solution to the system. It also has commands for splitting fractions into partial fractions, combining several fractions into one and. The algebra section allows you to expand, factor or simplify virtually any expression you choose. If we draw these two lines on a graph, we get one line that goes up at a steep angle, and one that goes down at a mild angle. QuickMath will automatically answer the most common problems in algebra, equations and calculus faced by high-school and college students. For example, let's say we're working with a system that contains the equations y = 3x - 2 and y = -x - 6.When you're working with a system of two equations, the solutions are the points on a graph that the lines for both equations cross at.

Often, algebra teachers use a graphing approach for solving these problems. Solving more than one equation at once may sound super-tricky, but when you're working with simple algebra equations, it's not actually that hard.

See How to Add Exponents for more information.Īsk your teacher to help you understand tricky algebra topics. For instance, in the equation 2x + 3x 2 = 10, we can't combine 2x and 3x 2 because the x variables have different exponents. This is also true for when one variable has a different exponent than another.In the equation 2x + 1y = 9, we can't combine 2x and 1y because they are two different variables. Note again that you can only add the same variables together.In this case, we can add 2x and 1x together to get 3x = 9. For example, let's look at the equation 2x + 1x = 9.In other words, x + x = 2x, but x + y doesn't equal 2xy. What do you do if the same variable appears more than once in the equation? Though this situation may seem tricky to solve, you can actually treat variables how you'd treat normal numbers - in other words, you can add them, subtract them, and so on as long as you only combine variables that are alike. If a variable appears more than once, simplify the variables.
