-4(y+1) - 2
=(-4y-4) -2
=-4y-6
you would need to divide 90 by 3 because that is how many there are in each row.
you will get 30
then you need to multiply 30 by 2 becanse that is how many are in the rows on the left.
you will get 60,
so there are 60 seats on the left.

<u>A formula is a fact or rule that uses mathematical symbols. It will usually have: an equals sign (=) two or more variables (x, y, etc) that stand in for values we don't know yet</u>.
Example: The formula for finding the volume of a box is:
x = 2y - 7 Formula (relating x and y)
a2 + b2 = c2 Formula (relating a, b and c)
The number zero belongs in the sets of integer and whole numbers
