Kenzi and her friends order popcorn and soda before the movie. The concession stand charges $9 for a tub of popcorn and $4 for a large soda. If the friends bought a total of 8 items and spent $57, how many tubs of popcorn did they purchase?

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

i think the length is 12 and the width is 17
