Solve the linear equations
-2x+5y=39
2x-3y=-25

Step-by-step explanation:

hello :

-2x+5y=39 (*)

2x-3y=-25(**)

add(*) and (**) : 2y =64    so : y =64/2 =  32

put this value in (*) : -2x+5(32) = 39 continu

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.
