4.   (a) Construct 3 equations starting with x = 2
(b) Construct 3 equations starting with x = – 2

(a) The 3 required equations can be :                                                                                                                            (b) The required equations are :

1. Solve the following equations:

$(a) 2y + \frac{5}{2} = \frac{37}{2}$

(b) 5t + 28 = 10

(c) a /5 + 3 = 2

(d) q/ 4 + 7 = 5

e) 5 x/2  = –5

(f) $\frac{5}{2}x = \frac{25}{4}$

(g) 7m + 19/2 = 13

(h) 6z + 10 = –2

(i)$\frac{3l}{2} = 2/3$

(j)$\frac{2b}{3}- 5 = 3$

Transposing  to the RHS :       (b)    5t + 28 = 10 Transposing 28 to the RHS and then dividing both sides by 5, we get  :       (c)  a /5 + 3 = 2 Transposing 3 to the RHS and multiplying both sides by 5, we get :           (d)  q/ 4 + 7 = 5 Transposing 7 to the RHS and multiplying both sides by 4:              (e)     5 x/2  = – 5 Multiplying both sides by  :     (f) ...
