Answer (a) 
(Transposing 
to R.H.S.)
Dividing both sides by 2,
(b) 5t + 28 = 10
5t = 10 − 28 = −18 (Transposing 28 to R.H.S.)
Dividing both sides by 5,
(c) 
(Transposing 3 to R.H.S.)
Multiplying both sides by 5,
a = −1 × 5 = −5
(d) 
(Transposing 7 to R.H.S.)
Multiplying both sides by 4,
q = −8
(e) 
Multiplying both sides by 2,
5x = −10 × 2 = −20
Dividing both sides by 5,
(f) 
Multiplying both sides by 2,
Dividing both sides by 5,
(g) 
(Transposing 
to R.H.S.)
Dividing both sides by 7,
(h) 6z + 10 = −2
6z = − 2 − 10 = −12 (Transposing 10 to R.H.S.)
Dividing both sides by 6,
(i) 
Multiplying both sides by 2,
Dividing both sides by 3,
(j)
(Transposing −5 to R.H.S.)
Multiplying both sides by 3,
2b = 8 × 3 = 24
Dividing both sides by 2,
b = 
= 12
