Solve the system of linear equations below.

2x + y = 5
x + y = 4

A. x = 1, y = 3

B. x = 1, y = 5

C. x = 3, y = 1

D. x = 9, y = -5

2×1+3=5

2+3=5

5=5

equal

1+3=4

4=4

equal

x=1,y=3

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
