I am sure it's One Solution
Answer:
(5,-1)
Step-by-step explanation:
x=5
y= -1
I'm assuming you're subtracting. It would be 3.9. The second one would be 0.65.
2400 + 100x = 2200 + 120x
2400 - 2200 = 120x - 100x
200 = 20x
200/20 = x
10 = x <== they would have to sell 10 systems
Answer:
subtract 10x from both sides
5x + 4 = 10x + 6
-10x -10x
subtract 4 from both sides
-5x + 4 = 6
<u> -4 -4</u>
-5x = 2
divide -5 from both sides
x = -2/5
