It would be a straight line
One hundred thirty nine thousand eight hundred fifty two
2400 + 100x = 2200 + 120x
2400 - 2200 = 120x - 100x
200 = 20x
200/20 = x
10 = x <== they would have to sell 10 systems
Hey there!
2x + 10
= 2(x + 5)
BECAUSE….
= 2(x + 5)
= 2(1x + 5)
= 2(1x) + 2(5)
= 2(x) + 2(5)
= 2x + 10
2x + 10 = 2x + 10 is true ✔️
Therefore, your answer is: 2(x + 5)
Good luck on your assignment & enjoy your day!
