Answer:

Computer is $866

Printer is $433

Step-by-step explanation:

We can form two equations given our variables:

Let's assume the computer=C and the Printer=P.

1) C+P=1299

2) 2P=C

Now we just plug in the 2nd equation into the 1st.

(2P+P)=1299

3P=1299

P=1299/3

P=433

Now that we know the value of the printer, we can subtract that from the total price:

1299-433=866

C=866
