Solve the equations embedded in the jpeg to find the flag. Solve this problem before solving my Scope challenge which is worth 100 points.

## ebouteillon

I love numpy. ðŸ™ƒ

## kcbowhunter

Excellent!

## yupwn

a bit tricky

## kcbowhunter

Glad you got it!

## kcbowhunter

Glad you got it!

## JPB-INFOSEC

Did it manually and took forever LOL

## kcbowhunter

Impressive to do it manually! I think Wolfram has a website which does mathematics.

## SeeTeeEff

each equation returns and x and y value right? are we providing x from the first equation and y from the second? or should each equation resolve to a single integer?

## kcbowhunter

There are two equations and two unknowns, so you have to solve the system of equations to solve for x and y. You can't solve just one equation or x or y, you have to solve them together. You can do basic linear algebra http://mathsfirst.massey.ac.nz/Algebra/SystemsofLinEq/EMeth.htm or https://www.youtube.com/watch?v=cz6UmZLWgEw or use Wolfram: https://www.wolframalpha.com/examples/mathematics/algebra/equation-solving/

very interesting

## kcbowhunter

Thanks, glad you enjoyed it. I have a 100 point challenge called Scope which also has a 2x2 set of equations to solve, and the solution is used to decrypt instructions for solving the challenge.
