If you would like to solve the system of equations 2x + y = -4 and y = 3x + 2, you can do this using the following steps:
<span>2x + y = -4
y = 3x + 2
</span>_________
<span>2x + y = -4
</span>2x + 3x + 2 = -4
5x = -4 - 2
5x = -6
x = -6/5
y = 3x + 2 = 3 * (<span>-6/5) + 2 = -18/5 + 10/5 = -8/5
</span>
(x, y) = (-6/5, -8/5)
The correct result would be (-6/5, -8/5).
Answer:
The laptop was 934 dollars.
Step-by-step explanation:
The equation you should use to solve this is 120 + 11 (74) since the down payment was a one-time thing and she pays 74 dollars for 11 months, not including the first month.
When you solve that, you will get 934 which is the correct answer.
Y= 3.94x Y is representing the total amount of money owed and x represents how many pounds of blueberries.
7/4=4/4+3/4=1+3/4=1 and 3/4
