Crazy for Math: Learn to love Algebra
In this website, I hope to enlighten you upon three of the most important equations in Algebra. These are the Linear and Literal equations and the equation for a line. After reading my problems and their solutions I hope that you will have a better understanding of them and how to use them.
Linear equation-An equation that can be written in the form AX = B. A and B are always constants and A can'tequal 0
How to solve a Linear Equation
| 3/7X + 9 = 15 | You need to start by copying the equation |
| 3/7X = 6 | You then need to subtract 9 from each side of the problem |
| X = 7/3(6) | Next, you should multiply both sides by the reciprocal of 3/7, which is 7/3. Doing so will get rid of the fraction |
| X = 14 | Finally, after you multiply by the reciprocal you will get a simplified answer of 14. |
As you see, it is very easy to solve a literal equation. All you really need to do is isolate the X and then plug the X back into the equation to find an answer.
Literal Equations-A Literal Equation is an equation that applies to a real life formula to find or identify a formula for a certain thing. While you can't really solve a literal equation, the point is to isolate one of the variables so you can find it's equation.
How to solve a Literal Equation
| D = RT (Distance = Rate x Time) | Solve for R |
| D/T = RT/T | You need to leave R by itself, so you need to divide both sides by T. |
| R = D/T | By isolating R, you find that you need to divide the Distance by the Time to determine the Rate. |
Equation for a Line- The equation of a line comes in the form of three different equations. These are the standard form, the point slope form, and the slope intercept form. You can use all 3 of these equations to find how a line is graphed. All of them give you the slope and Y-intercept, which is all you need to graph your line on a chart. I will explain these equations in the order of point slope, slope intercept, and then standard form. In all of these equations, you can use the Y to find the Y intercept and the m to find the slope of the line.
Equation of a Line
| Y-Y1 = m (X-X1) | This is Point Slope form |
| Y = mX + b | This is Slope intercept form, it is the most common equation for a line that you will find. It gives you the basics you need to find the equation of a line which is the m=slope and b= Y-intercept |
| aX + bY = C | This is the standard form for the equation of a line. |
