2x - 3y = 1 x = y + 2
solve the system using method of substitution and do a check to make sure PLEASE I BEG U

we have x = y +2

now we put that value in other eq.

2(y+2)-3y = 1

2y+4-3y = 1

2y-3y = 1-4

-y= -3 (cut the signs on both side)

y= 3

now we put y value in the other given equation

x = 3+2

x = 5

we have y as 3 and x as 5.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
