Answer:
Four boys and one girl.
Step-by-step explanation:
Total students wearing glasses = 5
Separate the students by x and x + 3. It is x + 3 for the boys because there are three more boys wearing glasses.
Girls = x
Boys = x + 3
Total = 5
<u>Calculate:</u>
x + x + 3 =5

2x = 2
x = 1
Boys wearing glasses = (1) + 3 = 4
Girls wearing glasses = 1
The answer is y=2x
