Answer:
y+1 1/4=3 3/4 or y.1 1/4=3 3/4
Step-by-step explanation:
Let's say x is J because it's Lemon Juice.
It's said that the pH of J is less than 4 so: pH(J) < 4 and pH(J) is greater than 1.5 so: pH(J) > 1.5
Now we can construct:
Or simply:
We can also write this with an interval:

2x²+13x-45 =(x+9)(2x-5)
3/(x+9)=[3(2x-5)]/[(x+9)(2x-5)]=(6x-15)/(2x²+13x-45)
