TOPIC: Forming and Solving Equations (An equation must be included as well please)

Tatiana [17]

1) let both have x ,
so putting in eqn ;

4x+0.50 = 9x-3
5x=2.50
x=0.50

therefore both have 50 p in the beginning !!

2) let the number be x

so in eqn;

(x+18)/2=5x
x+18=10x
9x=18
x=2

so the number must be 2 !!

if you have still any problem, comment !!
