let the number be n. Then: 2n = 3n ⇒ 2n - 2n = 3n - 2n ⇒ 0 = n ie, the number is zero.
What is 2n-5?
7
What is n in 5n plus 12 equals 3n?
5n + 12 = 3n Try to get all expressions with n on the left side 5n + 12 - 3n = 3n - 3n 2n + 12 = 0 Try to get rid of 12 on the left side 2n + 12 - 12 = -12 2n = -12 n = -12/2 = -6

How do you simplify the expression -5n --3n?
-2
What is 2n plus 3n?
5n = 2n + 3n .
How would you solve 3n-2n?
3n - 2n = n 3n - 2n = (3 - 2)n = 1n = n
What does n equal 3n plus 2n equals 25?
3n + 2n = 25 5n = 25 n = 5

7-2n=n-147-2n+2n=n-14+2n7=3n-147+14=3n21=3n21/3=3n/37=n
What is the answer to 3 plus 3n equals 9 plus 2n plus 4n?
3 + 3n = 9 + 2n + 4n n = -2
What is n in 5n plus 12 equals 3n?
5n + 12 = 3n Try to get all expressions with n on the left side 5n + 12 - 3n = 3n - 3n 2n + 12 = 0 Try to get rid of 12 on the left side 2n + 12 - 12 = -12 2n = -12 n = -12/2 = -6
Two times a number plus five is three times a number?
2n+5 = 3n 5 = 3n-2n 5 = 1n check 2n+5 = 3n 2x5+5 = 3x5 10+5 = 15 15 = 15
