Answer:
2. 5t - 3 = 3t - 5
=> 5t - 3t = -5 + 3
=> 2t = -2
=> t = -1
By putting -1 at place of t,
5(-1) - 3 = 3(-1) - 5
=> -5 - 3 = -3 - 5
=> -8 = -8
L.H.S = R.H.S
3. 5x + 9 = 5 + 3x
=> 5x - 3x = 5 - 9
=> 2x = -4
=> x = -2
By putting -2 at place of x,
5(-2) + 9 = 5 + 3(-2)
=> -10 + 9 = 5 - 6
=> -1 = -1
L.H.S = R.H.S
4. 4z + 3 = 6 + 2z
=> 4z - 2z = 6 - 3
=> 2z = 3
=> z = 3/2
By putting 3/2 at place of z,
4(3/2) + 3 = 6 + 2(3/2)
=> 6 + 3 = 6 + 3
=> 9 = 9
L.H.S = R.H.S
5. 2x - 1 = 14 - x
=> 2x + x = 14 + 1
=> 3x = 15
=> x = 5
By putting 5 at place of x,
2(5) - 1 = 14 - 5
=> 10 - 1 = 9
=> 9 = 9
L.H.S = R.H.S
