(e) x exceeds 3 by 7
 
Question 2
Solve the equations :
(a?)  $3(x-1) + 7 = 11   $
(b) $14 =  \frac {7x}{10}  -8$ 
(c?) $\frac {(x-3)}{5}  - 2 = -1$                   
(d) $20- (2x-5) = 25$
(e) $\frac {(y-7)}{3}  -1 = 0$
(f) $\frac {m}{4} -7 =3$
(g) $3z + 11 = 41$
(h) $4(x+ 1) = 16$
(i) $2x + \frac {1}{4} =\frac {7}{4}$
