I've been trying to find how to solve this system for hours with no luck, help please!

Given the linear system:

dx/dy = x-2y

dy/dt = z+4y

dz/dt = z

a) Find the general solution

b)Find the solution for the initial condition Y(0)=(-1,-1,-1)T

struc coord {

float x;

float y;

} pt1 = {1.1,2.2},pt2, *pt=&pt2;

how do i print out the values of the structure pt1?

I am currently using a corrective eye care cream, i am confused though on the how to use instructions it says to "use daily morning and evening just before the essence"....what does it mean by "just before the essence" ?

A cylinder of compressed gas is labeled "Composition (mole %) : 4.5% H2S, 3.0% CO2, balance N2." The pressure gauge attached to the cylynder reads 46 atm. Calculate the partial pressure of each gas, in atmospheres, in the cylinder.
