Set [math]z = x_1 + x_2[/math] and [math]w = x_1 - x_2[/math].
The first equation becomes [math]-w \leq 1[/math]. Rewrite it as [math]w \geq -1[/math]. The second one becomes [math]3.5 z - 2.5 w \leq 15[/math]. Pass [math]w[/math] to the other side on the last equation and get [math]3.5z \leq 15 + 2.5w \leq 17.5[/math]. That's [math]z \leq 5[/math].
