Question

Help me write a real world scenario for the following equation...

2x + y = 10
3x + 4y = 25
Solve this with me and help me explain what the results mean according to the scenario we will create together :D

Answer 1

I am Russian

Answer 2

u dnt know how to do this

Answer 3

There are two methods to solve this system of equations.
This is one of them !
From the 1st equation we can say that :
\[y=10-2x\]
So the 2nd equation becomes like this :
\[3x + 4(10-2x) = 25 \]
So :
\[3x+40-8x=25\]
So :
\[-5x=25-40\]
So :
\[-5x= -15\]
so :
\[x=\frac{-15}{-5}=3\]
And we return to the equation of y :
\[y=10-2x=10-2\times3=4\]
