Answer: <em>a + ( 2a - 7 ) = 41</em>
Explanation:
Let be "a" the Nicci's age and "s" the Nicci's sister.
You know that the sum of Nicci's age and her sister's age is 41. This can be represented with the following equation:
<em>a + 8 = 41</em>
And knowing that Nicci's sister is 7 years less than twice Nicci's age, you can write another equation to represent this:
<em>8 = 2a - 7</em>
Now, substitute the second equation into the first equation in order to find the equation that represents this relationship.
Then, this is:
<em>a + ( 2a - 7 ) = 41</em>

Answer:
x = 6
Step-by-step explanation:
1st Group like terms: 13x-5=10x-4x+37
2nd Add similar elements: 10x-4x=6x
13x-5=6x+37
3rd Add 5 to both sides: 13x-5+5=6x+37+5
4th Simplify: 7x=42
5th Divide both sides by 7: 7x÷7=42÷7
6th Simplify: x = 6
It can be either B. 11 or C. -11
