# Systems of linear equations: solving by addition

I have not understood this question. it confused me a lot. I have tried to solve it but the solution was senseless.

$$\begin{cases} 3x + 4y - 5 = 2x + 3y - 1\\ 6x - 2y + 2 = 4x - 3y - 5 \end{cases}$$

Can anyone help me with this?

$$\begin{cases} Ax + By = C\\ Dx + Ey = F \end{cases}$$
This can be done by combining the $x$ and $y$-terms on the left and moving the constant terms to the right. Then solve this "normal-looking" system using addition.
