find the solution to the following system using substitution or elimination: y = 2 x + 6 y / = –3 x + 11

  (x, y) = (1, 8)

Step-by-step explanation:

Maybe your equations are ...

Equating the values of y, we have ...

  2x +6 = -3x +11

  5x = 5 . . . . . . . . . . add 3x-6

  x = 1 . . . . . . . . . . . divide by 5

  y = 2(1) +6 = 8

The solution is (x, y) = (1, 8).

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.

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
