Answer:
Number of sweets =54
Step-by-step 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
