How To Do Linear Math Homework In An Hour: Helpful Advice
Many students have problems solving math problems. Some say that doing homework can turn into a torture if it includes linear equations. As they are polynomial equations, there are many figures and sometimes more than one variable there. Moreover, very often learners are required to draw graphs of these equations which are even more intimidating. However, just like any math problems, you can solve linear equations easily if you know how to solve them and what to start with.
What are Linear Equations?
First of all, let’s see what linear equations aren’t and what they don’t contain:
- Linear equations don’t contain variables with exponents.
- That is, y2 or x3.
- Linear equations square root signs on variables.
- That is, no √x or √z here.
- If there’s more than one variable, you can’t multiply a variable by a variable.
- You can’t multiply x by y or y by z in a linear equation.
- Dividing a variable by a variable is impossible, too.
- You can’t divide x by y or a by b.
With that said, linear equations are polynomials of degree 1 where you must isolate the unknown variable to solve the equation. If you’re required to draw a graph for a linear equation, remember that the name speaks for itself – a linear equation is always a straight line.
How Do I Solve My Linear Math Homework?
To solve a linear equation, you must do the same kind of thing to both sides of the equation. That is, if you subtract or add something the left side, you must subtract or add the same number on the right side as well. Here is a simple example with one variable:
x + 10 = -10
As we need to isolate our x, we have to subtract 10 from both sides of the equation. That is, 10-10 = 0, and -10-10 = -20. This is what we get:
You can apply this rule to any kind of linear equation you’ll ever see: in order to solve it, you have do the same thing on both sides of the equation. Yes, it’s as simple as that.
To sum it up, here is what you must do to do your linear math homework fast and easily:
- Prepare a pen and a spare sheet of paper.
- Read the assignment carefully.
- Concentrate on the equation.
- Isolate the variable by doing the same thing on both sides of the equation.
- Check whether you didn’t multiply/divide a variable by a variable.
