Tutorial; Finding the "X" Value In A Mathematical Equation!

Question

Imagine · Answer

How do I find the "x" in mathematical equations? Well, This tutorial is here to help you!

Imagine · Answer

Given the Equation 5x+5=40 You would subtract the number "5" from "40" which gives you "35"

Imagine · Answer

Then, you would see the equation 5x=35. Furthermore, you would divide 5 on each side. Which then would look like...

Imagine · Answer

$$\frac{ 5 }{ 5}=\frac{ 35 }{ 5 }$$

Imagine · Answer

So your final answer would look like... X=7

Imagine · Answer

Let's do another one, Shall we?

Imagine · Answer

Let's say 4(x+7)=48 The First thing that will be done is multiplying the 4 to everything in the parenthesis

Imagine · Answer

$$4x+28=48$$

Imagine · Answer

Then you would then subtract "28" from "48". Which then the equation would look like...

Imagine · Answer

$$4x=20$$

Imagine · Answer

You would then divided each side by 4... Just like we did in the first equation.

Imagine · Answer

$$\frac{ 4x }{ 4}=\frac{ 20 }{ 4 }$$

Imagine · Answer

So, your final answer would look the same as the first one... X=5
