Answer 2

1) 34 - 5(p + 1) = 4
34 - 5p - 5 = 4
29 - 5p = 4
-5p = 4 - 29
-5p = -25
p = 25/5
p = 5

Verification---
L.H.S = 34 - 5(p + 1)
Now, p = 5
then,
L.H.S = 34-5(5+1)
= 34-25-5
= 4
Now L.H.S = R.H.S, Hence verified.


2) 28 = 4+3(t-5)
28 = 4+3t-15
28 = -11 + 3t
28 + 11 = 3t
39 = 3t
39/3 = t
13 = t


Verification---
R.H.S = 4+3(t-5)
Now, t = 13
So, R.H.S = 4+3(13-5)
= 4+39-15
= 13
Now R.H.S = L.H.S Hence verified
