Answer:
Infinitely many solutions.
Step-by-step explanation:
Step: Solve 2x + 8y = 6 for x:
2x + 8y = 6
2x + 8y + −8y =6 + −8y (Add -8y to both sides)
2x = −8y + 6
2x/2 = (-8y + 6)/2 (Divide both sides by 2)
x = −4y + 3
Step: Substitute −4y + 3 for x in −5x − 20y = −15:
−5x − 20y = −15
−5 (−4y + 3 ) −20y = −15
−15 = −15 (Simplify both sides of the equation)
−15 + 15 = −15 + 15 (Add 15 to both sides)
0 = 0

Answer:
12:45
10:45 + 15 minutes = 11:00
11:00 + 1 hour and 45 minutes = 12:45
Think of it as:
