To solve the equation 9x = 21, you would first need to isolate the variable x by dividing both sides by 9. This would give you x = 21/9, which simplifies to x = 7/3 or x = 2.33 (rounded to two decimal places). Therefore, the value of x that satisfies the equation 9x = 21 is x = 7/3 or x = 2.33.
Well 63 divided by 3 equals 21. So 3 times 21 equals 63. 21 is that number.
63 ÷ 3 = 21.
315/21 = 15, hence 15 times 21 is 315
