Step-by-step explanation:
Since X is given to you (in this case, it’s 7), all you have to do is plug it into the equation.
1. -2(7) + 10
When a variable or a number is directly outside a number, it means you should multiply the two numbers, no matter what.
Now that we know this: -2 * 7 = (-14) When a negative is multiplied by a positive, it turns out negative.
2. (-14) + 10: Let’s say (for instance), that I owe 14 dollars to a friend. If I pay 10 of it, how much do I owe my friend? It would be -4 because you’re still in debt, and haven’t payed your friend all of her 14 dollars back.
3. You should come up with an answer of (-4) because of all of the steps given.
If something doesn’t make sense, please make a note of it and tell me. Otherwise, have a splendid day.
Henrietta solved a rational equation by multiplying both sides by 
.She did not find the least common multiple of the denominators .If she had find the least common denominator which is 3x(x+2) then the question can have been simplified in more simpler form.
Henrietta can have got rid of denominator and then use the distributive rule .
So the first option
A:She could use the least common multiple of the denominator is right

Step-by-step explanation:
Marcus would need to save for 24 weeks in order to purchase a new electronic keyboard.
<h3>Define the meaning of the equation?</h3>
A mathematical assertion in which you use mathematical symbols to demonstrate that two sums are equal.
As per specified data-
- Marcus wishes to save $378 so that he can purchase a new electronic keyboard.
- Every week, he saves $15.75 from his paycheck.
Let 'x' be the number of weeks required to complete the amount.
The equation becomes.
378 = 15.75x
For the number of week required.
x = 378/15.75
x = 24
Thus, Marcus would need to save for 24 weeks in order to purchase a new electronic keyboard.
