## Main Question or Discussion Point

How would you express one function as Linear combination of other? For example the following sets

{1,x+2,3x-5}

{e^x,e^(2x),xe^x,(7x-2)e^x}

How would i go about solving this?

Should I start with equating one function to the other two in first example?

like x+2=1+(3x-5) ?

Thanks
