# 4. Solve the following equations:(a) 10p = 100(b) 10p + 10 = 100(c) p /4 = 5(d) – p/3 = 5(e) 3 p/4 = 6 (f) 3s = –9(g) 3s + 12 = 0(h) 3s = 0(i) 2q = 6(j) 2q – 6 = 0(k) 2q + 6 = 0(l) 2q + 6 = 12

(a) Divide both sides by 10, we get :

(b) Transposing 10 to the RHS, we get :

Now, dividing both sides by 10 gives  :

(c) Multiplying both sides by 4, we have :

(d) Multiplying both sides by - 3 , we have  :

(e) Multiplying both sides by , we have :

(f) Dividing both sides by 3, we have :

(g)  Transposing 12 to the RHS and then dividing both sides by 3, we have :

(h) Dividing both sides by 3, we get :

(i) Dividing both sides by 2, we get :

(j)  Transposing - 6 to the RHS and then dividing both sides by 2, we get  :

(k) Transposing 6 to the RHS and then dividing both sides by 2, we get  :

(l) Transposing  6 to the RHS and then dividing both sides by 2, we get  :
