Answer:
The solution is x = 9, y = -1.
Step-by-step explanation:
x + y = 8
x - y = 10 Adding to eliminate y:
2x + 0 = 18
x = 9 Substituting x = 9 into the first equation:
9 + y = 8
y = 8 - 9
y = -1..
It's C, which is 12. Because 6x2 = 12 and 4x3 = 12 :)
Answer: 350 + 5.2x = V
Step-by-step explanation:
350 + 5.2x = V
5.2x represents adding 5.2 gallons per minuet
350 means adding the initial 350 gallons
= V represents the total amount of water
The answer is 2, simplify it by dividing 4 and 2 by 2
