Ok so I think what you need to be solved is to find h? So I am gonna do that

To find h the first thing you need to do is get the variable h all on one side. So subtract 6.5h from the right side and subtract 5 from the left side. It will then look like this:

0.75h = 5.25

Now you need to isolate the variable so you must divide both side by 0.75 to get h by itself. This should now look like:

h = 7

So now you know that h is equal to 7

You can always check to see if the answer is correct by plugging in 7 for h on both sides and seeing if they equal the same amount.

Hope this helps :)

Peter the optician sees 16 patients one Tuesday.4 are neither short nor long sighted,the total number of short sighted patients

My name is Ann [436]

The number of short-sighted patients is 7

The number of long-sighted patients is 5

The number of patients requiring a varifocal lens is 4

Step-by-step explanation:

Stepwise solution-

Throughout the question, only 3 types of patients are mentioned. Hence, it would be safe to assume that he saw/sees these 3 types of patients on Tuesday.

As per the given details-

4 are neither short-sighted patients nor long-sighted patients. Then it means no of varifocal lens patients is 4.

Hence remaining total patients=16-4=12

As given, no of short-sighted patients is 2 more than the number of long-sighted patients.

Let us assume the number of long-sighted patients as “x”

Thus, the number of short-sighted patients would be “x+2”

x+(x+2)=12 (total remaining patients)

2x=10

x=5

Hence, No. of long-sighted outpatients = 5

No. of short-sighted outpatients =7
