Helps with this math problem please

First we are going to express both equation in terms of  y to compare their slopes:
For our first equation:
-x=1-y
-x-1=-y
y=x+1
For our second equation:
-1+y=x+2
y=x+3
So now we have our system of equations in terms of y:
\left \{ {{y=x+1} \atop {y=x+3}} \right.
Notice that the slope, the coefficient of x, in both equations is the same: 1, and if tow linear equations have the same slope, they are parallel.

We can conclude that we can classify the system of equations as parallel.

Gold’s gym charges $30 membership fee plus $3 for each workout, while Titletown charges $40 membership fee plus $1 for each work
ollegr [7]

Answer:

5 workouts should be performed to equalize the costs between both gyms.

Step-by-step explanation:

Given that Gold’s gym charges $ 30 membership fee plus $ 3 for each workout, while Titletown charges $ 40 membership fee plus $ 1 for each workout, to determine how many workouts does a person have to do until the total costs are equal, the following calculation must be performed:

Gold's Gym: y = 30 + 3x

Titletown Fitness: y = 40 + x

Gold's Gym: y = 30 + 3x2 = 36

Titletown Fitness: y = 40 + 2 = 42

Gold's Gym: y = 30 + 3x3 = 39

Titletown Fitness: y = 40 + 3 = 43

Gold's Gym: y = 30 + 3x4 = 42

Titletown Fitness: y = 40 + 4 = 44

Gold's Gym: y = 30 + 3x5 = 45

Titletown Fitness: y = 40 + 5 = 45

Thus, 5 workouts should be performed to equalize the costs between both gyms.
