Answer:
-5/14
Step-by-step explanation:
When adding fractions, you need to have a common denominator, the bottom part of a fraction. Because one denominator is 14 and the other is 7, you must create a new denominator.
To create a new denominator, you can either reduce a fraction or multiply it by something, which is easier.
For this problem, we can convert 2/7's denominator into 14 instead of 7 by multiplying the fraction by 2/2:
<u>2</u> x <u>2</u> = <u>4</u>
7 2 = 14
2/7 has now converted into 4/14. Now, we can easily add.
-9/14+4/14 This can be rewritten as something more understandable.
4/14-9/14 We are now subtracting.
-5/14 This cannot reduce, so it is our answer.

Answer:
-27 and -18
Step-by-step explanation:
Solve algebraically. Use a variable and an expression to represent the numbers.
let the smaller number be "x"
The bigger number is x + 9.
The two numbers are "x" and "x + 9".
The sum of two numbers means when you add them together. If their number is −45, then:
x + x + 9 = −45
Simplify and isolate "x" to solve in the equation.
x + x + 9 = −45 Collect like terms (numbers that have "x") to simplify
2x + 9 = −45 Isolate "x"
2x + 9 - 9 = −45 - 9 Subtract 9 from both sides
2x = −54
2x/2 = −54/2 Divide both sides by 2
x = -27 Value of smaller number
The bigger number is x + 9. Substitute "x" for -27 and solve.
x + 9
= -27 + 9 Add together
= -18 Value of bigger number
Therefore the two numbers are -27 and -18.
