1) 17-12n=3n-13
17+13=3n+12n
30=15n
2=n
2) 6x+5=7x+3
6x-7x=3-5
-x=-2
x=2
3) 15+4y=y
4y-y=-15
3y=-15
y=-5
4) 24-15m=15-14m
24-15=-14m+15m
9=m
5) -10z+75=-5z
-10z+5z=-75
-5z=-75
z=15
6) 6n-35=n
6n-n=35
5n=35
n=7
7) 18-12x=25-13x
-12x+13x=25-18
x=7
8) -7m-33=4m
-33=4m+7m
-33=11m
-3=m
9) 15z+14=14z-9
15z-14z=-9-14
z=-23
10) 17-8y=4y-7
