Question

Glenda has some sweets. If she gives each of her friends 6 sweets, there will

be none left. If she gives each of them 4 sweets instead, she will have 18 left.
How many sweets does she have?
​

Answer 1

Number of sweets =54

Explanation:

Let number of friends = x

Number of sweets = y

Glenda gives 6 to each of her friend,

6x = y ----------------(I)

If she gives each of them 4, 18 is left

4x + 18 = y ---------------(II)

From (I)& (II)

6x = 4x + 18

Subtract 4x from both sides

6x - 4x = 4x + 18 - 4x

2x = 18

Divide both sides by 2

2x/2 = 18/2

x = 9

y = 6x

= 6 * 9

y = 54

Number of sweets =54
