Solve the system of equations.

-5x + 4y = 3
X = 2y - 15

x=9

y=12

Step-by-step explanation:

. Substitute the given value of x into the equation so... -5(2y-15)+4y=3

. y=12

. Substitute the given value of y into the equation x=2y-15 so... x=2 x 12-5

. x=9

.The possible solution of the system is the ordered pair (x,y) so... (x,y)=(9,12)

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
