Step-by-step explanation:
15) 13x = 130 x = 10
16) 16x+2+43x+1 = 180 59 x = 177 x = 3
17) 29x+3+31x-3 = 180 60x = 180 x = 3
18) 16x -5 + -5 + 22x = 180 38x = 190 x = 5
We will have the following:
First, we solve both equations for y, that is:


&


From this we can see that they are parallel lines, that do not share any common points, so there is no solution for the system.
