Solving Algebra word problems is useful in helping you to solve earthly problems.  While the 5 steps of Algebra problem solving are listed below, this article will focus on the first step, Identify the problem.

Javier is making brownies to serve at the family picnic.  If the recipe calls for 2 ½ cups of cocoa to serve 4 people, how many cups will he need if 60 people attend the picnic?

[[Image:]]Two step algebraic equations are relatively quick and easy -- after all, they should only take two steps. To solve a two step algebraic equation, all you have to do is isolate the variable by using either addition, subtraction, multiplication, or division. If you want to know how to solve two step algebraic equations in a variety of ways, just follow these steps.

Enter expression, e.g. (x^2-y^2)/(x-y) Sample Problem Simplify

Enter expression, e.g. x^2+5x+6 Sample Problem Factor

Have you ever given up working on a math problem because you couldn’t figure out the next step? Wolfram|Alpha can guide you step by step through the process of solving many mathematical problems, from solving a simple quadratic equation to taking the integral of a complex function.

When trying to find the roots of 3 x 2 + x –7=4 x , Wolfram|Alpha can break down the steps for you if you click the “Show steps” button in the Result pod.

this is not a quadratic trinomial because there is not exponent of 2. In fact, this is not even a trinomial because there are 2 terms

It's always easier to understand a new concept by looking at a specific example so you might want to do that first. This formula works when 'a' is 1. In other words, we will use this approach whenever the coefficient in from of x 2 is 1. (If you need help factoring trinomials when $$a \ne 1 $$ , then go here.

Multiply by -5 to take the 5y and -5y away (-5) x = y - 7 (1) 2x = 5y - 2 ---------------------------- -5x = -5y + 35 2x = 5y - 2 ---------------------- -3x = 33 divide both side by -3 x = -11 now choose of the two equation and substitute the x value x = y - 7 -11 = y - 7 y = -4 so ur solution is (-11,-4)
