x=19,z=17,Y=−5.3,and the second x=1.1.

Explanation:

For the first equation, we need to move -10 on the other side. To do so, we add 10 on both sides. This leaves us with x=19. For the second equation, we need to move 1 on the other side. To do so, we subtract one on both sides. This leaves us with z=17. For Y, we do the same with what we did for Z and we subtract 1.6 on both sides, leaving us with, Y=−5.3. Finally, for the second X, we subtract 2.7 on both sides leaving us x=1.1.
