3x-5=13
Move -5 to the right side and change the sign
3x=13+5
Add 13+5
3x=18
Divide both sides by 3
X=6

Option C
Step-by-step explanation:
1st day
8 hours = 420 circuits

Answer:
X = 5/2
Step-by-step explanation:
I will assume that you meant (1/5)X + 1/2 = 1. The LCD is 10.
Multiplying both sides by 10, we get:
2X + 5 = 10, or 2X = 5, or X = 5/2
