I wrote this for math class, does it make sense?A very famous equation, Euler’s identity relates the seemingly random values of

pi, e, and the square root of -1. It is considered by many to be the most beautiful equation in mathematics.
A more general formula is

e^{i x} = \cos x + i \sin x

When x = \pi , the value of \cos x is -1, while i\sin x is 0, resulting in Euler’s identity, as -1 + 1 = 0.

Also please don't hate I am only in sixth grade...

2x + 3y= 22<br> -2x +5y=-6
sasho [114]

The solution is x = 8 and y = 2

<em><u>Solution:</u></em>

<em><u>Given are the system of equations</u></em>

2x + 3y = 22 -------- eqn 1

-2x + 5y = -6 ----- eqn 2

We can solve the system of equations by elimination method

<em><u>Add eqn 1 and eqn 2</u></em>

Eqn 1 + Eqn 2

2x + 3y -2x + 5y = 22 - 6

0x + 3y + 5y = 16

8y = 16

Divide both sides of equation by 8

<h3>y = 2</h3>

Substitute y = 2 in eqn 1

2x + 3(2) = 22

2x = 22 - 6

2x = 16

<h3>x = 8</h3>

Thus the solution is x = 8 and y = 2
