Answer:
PEMDAS
Step-by-step explanation:
Using PEMDAS or the order of operations, you first multiply 2 by 6
2-2×6+3
2-12+3
Then you can go in any order since addition and subtraction take the same precedence.
-10+3=-7
X: earn per hour during the week
y: earn per hour during the weekend
13x + 14y = 250.90
15x + 8y = 204.70
Multiply the first equation by 4 and the second equation by 7
52x + 56y = 1003.6
105x + 56y = 1432.90
Subtract the first equation from the second:
53x = 429.30
x = 429.30/ 53
x = 8.10
Solve any of the equation for y:
15x + 8y = 204.70
y = [204.70 - 15(8.10)]/8 = 10.40
y - x = 10.40 -8.10 = 2.30
Answer: she earns $2.30 per hour more during the weekend than during the week.
Integers are numbers without decimals
The integers could you have multiplied are 9 and 2
Let the numbers be x and y
So, we have:

Increase x by 1 and reduce y by 1.
So, we have

Open brackets

Subtract xy from both sides

Collect like terms


Rewrite as:

The above means that, the difference between the integers is 7.
There are several integers that fit the above <em>description</em>;
One possibility is: 9 and 2
