Algebra Basics

Algebra is quite an interesting topic, which many people struggle on,

However I will explain the basics of it, the basics is that everything should be balanced in every equation question

for example if there is a question of 2x+8=12x, you would need to make the xs balance in one side, whilst the number (being 8, here) is with its kind of numbers, so now the equation reads 8=12x-2x, as the 2x moves over it becomes from positive to negative, so it is 12x-2x which gives 10x, so now the equation is 8=10x

So now 10 divide by 8= 10/8=5/4 as a fraction.

Another example is 6+3x=12x-4

Balance the equation so its 6+4=12x-3x, which is 10=9x

9 divided by 10=9/10, and leave it as that.

With this basic rule of algebra, it is compulsory that people who struggle on algebra should know this rule as the basics, and also by knowing the balance of equations such as this should help when doing more complex algebraic equations. So to sum up, remember balance the x numbers with its kind and the normal numbers with its kind, note, that the letter could be anything, not just x, but even y or m etc.

I will give more examples such as the question,

12X +9= 4X -8

Now I allow the time for you to work it out, it should take less then a two minutes work out.

Now I will reveal the answer

12X – 4X= -8-9

8X=-17

X=17/8

Now for Mixed fraction the answer is 2 1/8

Because 8 times 2=16

16+1=17 so therefore in mixed fraction the answer is 2 1/8

The equation may also be balanced by a device called a variable. A variable is a unknown number represented by any letter in the alphabet (often X). The ...
