解方程!!!

1. 43-13p+17=2p
43+17=13p+2p
60=15p
15p=60
p=60/15
p=4

2. 9b-1=3b+11
9b-3b=11+1
6b=12
b=2

3. 8-2x=4x-10
8+10=4x+2x
18=6x
x=18/3
x=6

4. 46-3y=22-9y
9y-3y=22-46
6y=-24
y=-4

5. 15+13x-39=10x-16-7x
13x-10x+7x=-16-15+39
10x=40
x=40/10
x=4

1.
43-13p+17=2p
2p+13p=43+17
15p=60
p=15

I will give you a chance to do the rest as exercises.

43-13p+17=2p
26=-1p
p=-26
