Answer:
(1) 3x-1 =28
3x = 29
x= 29/3
(2) 2x + 7 = 19
2x = 12
x=6
(3) 2p+14=0
2p=-14
p=-7
(4) 3q=21
q= 21/3=7
(5) 7y = 0
y=0/7=0
(6) 3/7x=6
7x×6=3
42x=3
x=14
(7) 4x+3=7x-3
3x = 6
x=2
(8) 5-3x=3-5x
2x=-2
x=-1
(9) x+11=5x-25
4x=36
x=9
(10) -m/3=4
-m=12
m=-12
(11) 5p/2=15/2
5p=15
p=3
I hope this will help you
