What is the value of the x variable in the solution to the following system of equations?

4x _ 3y = 3
5x _ 4y = 3

The two equations given in the question are

4x _ 3y = 3
And
5x _ 4y = 3
Multiplying the first equation by 4 and the second equation by 3, we get
16x - 12y = 12
15x - 12y = 9
Subtracting the second equation from the first equation, we get
x = 3

I hope the above procedure is clear enough for you to understand. I hope that this is the answer that you were looking for and the answer has actually come to your great help.

the flux of the flow field F across σ = 135

Step-by-step explanation:

Given that :

F = 2xi + 3yj

and σ is the cube with opposite corners at (0,0,0) and (3,3,3) oriented outwards.

Using divergence theorem,

f = 2 +3 = 5

where ;

F = 2xi + 3yj

Thus , the triple integral can now be ;

= 5(3)(3)(3)

= 135
