Question

Solve this
15x + 8y = $214

Answer 1

To solve this, rewrite the equation in terms of y, that is, get y on a side by itself.

Answer 2

what

Answer 3

So if we start with 15x + 8y = 214, let's isolate the 8y.
To isolate it, let's subtract 15x from both sides.

15x + 8y = 214
-15x - 15x

We get 8y = 214 - 15x

Answer 4

Do you understand what I did? Whatever we do to one side, we must do to the other.

Answer 5

x=?
y=?

Answer 6

In this case, all you would be able to find are maximums of x and y. You will not be able to evaluate completely.

Answer 7

They are asking for a simplified equation.

Answer 8

x=10
y=8

Answer 9

That is only one set of possible solutions. There are an infinite amount of solutions.

Answer 10

the solution is actually a line on a graph and not a single set of numbers.
