4 th Grade Math Algebra Solve for an unknown number represented by a letter Jessica Corriere & Robert Richards

### Use letters, boxes, or other symbols to stand for any number in simple expressions or equations (e.g., demonstrate an understanding and the use of the concept of a variable).  :

Use letters, boxes, or other symbols to stand for any number in simple expressions or equations (e.g., demonstrate an understanding and the use of the concept of a variable).

### Which number is symbolized by n?   6 x n = 48   A. 6 B. 7 C. 8 D. 9:

Which number is symbolized by n ?   6 x n = 48   A. 6 B. 7 C. 8 D. 9

### How to solve   Understand how to solve for the unknown. 6 x n = 48 Both sides must be treated the same Divide both sides by 6 to get the n alone on one side (6 x n) ÷ 6 = 48 ÷6 n = 48 ÷6 n = 8   Choice C has the correct answer *** You understand it when you can explain it:
