How do i solve this using elimination to get an ordered pair?

The ordered pair would be (-2, 1)

Step-by-step explanation:

To solve and get an ordered pair, we need to get a term to cancel. We can do this by multiplying the entire second equation by 2

4x + 3y = -5

-4x + 4y = 12

7y = 7

y = 1

Now that we have the value of y, we can use it to find x.

-2x + 2y = 6

-2x + 2(1) = 6

-2x + 2 = 6

-2x = 4

x = -2

42 inches then 10 1/2 deep

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
