    if we add tose equations, together, we get: \[\left( {d + e} \right) + \left( { - d + e} \right) = 1 + \left( { - 5} \right)\] please simplify

    no, since if we simplify that expression above, we get: \[\begin{gathered} 2e = - 4 \hfill \\ e = ...? \hfill \\ \end{gathered} \]

    now, please substitute e=-2, into the first equation, namley: \[d + e = 1\]

    hint: we get: \[d + \left( { - 2} \right) = 1\] what is d?
