Since both equations are equal to y, we can just combine them like this:

1/3x-3=-x+5

1/3x=-x+8

4/3x=8 (since x is 1x which is 3/3x)

x=6

Plug x back in:

y=-6+5

y=-1

So x=6 and y=-1

Hope this helped!

Since there is a $5 delivery charge, Valerie will surely spend those money.

Also, since a salad costs $7, and Valerie buys 3 of them, she will spend 21 more dollars.

So, salads and delivery charge sum up to $21+5 = 26$

This means that Valerie has $50-26 = 24$ dollars left. A drink costs $3, so she can buy

$\dfrac{24}{3} = 7$ drinks.
