4x-3y= -9

3x+2y= -11

solve the system of equations.

x = -3

y = -1

Step-by-step explanation:

Use elimination method-

Method where you eliminate one variable and find the value of the other.

Eliminate x-

1. Want to completely remove the x variable so you multiply 4 and 3 to a common gcf and you multiply one equation with a negative number.

-3(4x - 3y = -9)

4(3x + 2y = -11)

Multiply each term

-12x + 9y = 27

12x + 8y = -44

17y = -17

Get rid of 17

y = -1

Substitute -1 into the equation and solve for x

4x -3(-1) = -9

4x + 3 = -9

4x = -12

x = -3

Final answers:

y = -1

x = -3

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
