How many solutions in the equation 3x + 5 = -2x + 5*​

Isolate the variable by dividing each side by factors that don't contain the variable.

x=0

Step-by-step explanation:

one solution (x=0)

Step-by-step explanation:

First, let's simplify the equation to 3x=-2x (we subtract 5 from both sides). Now we can add 2x to both sides to get 5x=0. There is only one solution to this (x=0).

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).
