Question

fequal weights are put in the two pans, we find that the
9 is r=s
(iii) the root of 5x – 8 = 2x – 2 is x = 2 (iv) the root of 8 - 7y = 1 is y = 1
z
(v) the root of - = 8 is z = 56
7
4. Solve each of the following equations by the trial-and-error method:
(i) y + 9 = 13 (ii) x - 7=10 (iii) 4x = 28 (iv) 3y = 36
(v) 11 + x = 19
(vi)
(vii) 2x - 3= 9 (viii)

(ix) 2y + 4 = 3y

(x) 2-3 = 22 - 5
SYSTEMATIC METHOD FOR SOLVING AN EQUATION
