-5.8 + 2.6
We can rewrite this equation so it's easier to read like this:
2.6 - 5.8 (the answer will still be the same)
In the original equation, you're simply adding 2.6 to -5.8.
In the new equation, you're taking 5.8 away from 2.6.
An easy way to solve this is to ask "what's the difference between 5.8 and 2.6?", which is 3.2.
The answer to this problem is -3.2, because we're taking a larger number away from a smaller number.

Answer:
The number of the television sets that is model p is 12
Step-by-step explanation:
Here we have total number of television sold = 40
The model p televisions sold for $30 less than the model q televisions
That is $P = $q - $30
Therefore
Let the quantity of the model p sold be X
Let the quantity of the model q sold be X
Therefore
x + y = 40
Total cost of the television = 40 * 141 = $5640
Therefore, 120*x + 90*y = 5640
Plugging in x = 40 - y in the above equation we get
4800 - 30y = 5640 or
y = -28 and
x = 68
If we put y = 40 - x we get
30x + 3600 = 5640
If we put
120*x + 150*y = 5640.........(3)
we get
x = 12 and y = 28
Therefore, since the model p sold for $30 less than the model q, from the solution of equation (3) the number of the television sets that is model p = 12
