    Are you trying to solve for both \(C_1\) and \(C_2\)?

    Well. The first step is to rearrange the equation get one variable by itself. I can show the first one: \[-1=C_1+C_2\]\[C_1=-1-C_2\]Can you do for the other equation?

    Well, isn't the other one already in terms of c1?

    Exactly. Now, can you susbtitue them together?

    \[-1=c _{1}+c _{2}\] \[c _{1}=\frac{ -3c _{2} }{ 2 }\] now we have \[-1= \frac{ -3c _{2} }{ 2 }+c _{2}\] now solve for c2 made both terms on right with same denominator \[-2= \frac{ -3c _{2} }{ 2 } + \frac{ 2c }{ 2 }\]

    Now, you can substitute them together as: \[-1-C_2=\frac{-3\times C_2}{2}\]
