PLZ HURRY IT'S URGENT!!
Y_Kistochka [10]

Answer:

n + 6 = 7n

Step-by-step explanation:

"The sum of a number and six" would mean the number plus 6: n+6 and "is seven times the number" indicates that it would be equal to the product of 7 for n: 7n. According to this, the answer is that the translation of the sentence into an equation is: n+6=7n.

n − 6 = 7n is not right because the statement says the sum of a number and six.

7(n + 6) = n is not right because the statement indicates that seven multiplies n on the right side as it says seven times the number.

n = 7n + 6 is not right because the statement says the sum of a number and six which would be on the left side and that this would be equal to seven for n.
