Answer:

X=2

Step-by-step explanation:

5(4x-1)-2x=31

Distribute the 5

20x-5-2x=31

18x-5=31

18x=31+5

18x=36

When you divide you get 2

Translate to an algebraic statement. "The quotient of twice a number and 7 is 20."

Answer:

Translation: 2x/7 = 20

Step-by-step explanation:

When we listen to the word "quotient", it means the solution to a division problem.
An unknown number that has been multiplied by 2 is in the numerator because it came before the 7 in the statement.
The number "7" is in the denominator because it came after the 2x in the statement.
The word "is" represents an equal sign.
The solution to the division problem (quotient) is 20.

If we put these clues together, we get 2x/7 = 20 as our translated equation.

Hence, our algebraic statement is 2x/7 = 20. The key is to listen to the statement.
