6x + y = -1
y=-3x - 4

x = 1, y = 7

Step-by-step explanation:

If y = -3x - 4, then

6x -3x -4 = 1

3x - 4 =-1

3x = 3

x = 1

If x = 1, then

y = -3*1 -4 = -3 -4 = -7

could you reply to this with the question so i can ?

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
