First, you set up your equation.

let's now get rid of the negative 4 and move it to the other side so we can set up another equation.

Now, we can cross multiply to get x

x= 28

(The picture should help you a little bit :) )

Hope this helps!

First multiply both sides by 7

Your equation now looks like this:

x-28=0

Now move the constant to the other side causing it to change signs

The negative now becomes a positive

x=28

Now you are left with your answer:

x=28

Hope this helps! :3

____ [38]

Answer:

6

Step-by-step explanation:

maximum calories in a day = 540

no. of calories from the dog food = 320 x 1 \frac{1}{2}

                                                       = 480

∴ she can have:  540 - 480

                          = 60 calories to stay inside calorie range

no. of new treats she can have = 60 ÷ 10

                                                    = 6

Hope this helps!
