Death Valley is a desert in northern California with many place of interest. One such place is the Badwater Basin, the elevation is -282 feet. At another location, Salt Creek Trail, the elevation is-220 feet. Write an inequality to compare the elevations and state
which elevation is closer to sea level.

(-3,2)

Step-by-step explanation:

Solving by substitution involves taking one of the equations and basically plugging it into the other.

I would start by taking the first equation and rearranging it to equal a variable. It will be easier to solve using this equation as the x variable is already isolated.

Take:

Subtract 3y to the other side:

Now plug this equation in for the value x into the other equation like so:

Now there is only one variable to solve in this new equation. Solve for the value y.

Distribute -2:

Combine Like Terms:

Add 6 to both sides to cancel:

Divide by 9 to both sides to cancel 9:

So the value y=2.

Now we can plug the value of y back into either equation to now solve for x.

Now you have the point (-3,2)
