Question

Nine more than 3 times a number is the same as 6 less than twice the number

Answer 1

Explanation:

Let the number = x

3x + 9 = 2x - 6 Looks like you are going to get something negative here.

Subtract 2x from both sides.

3x - 2x + 9 = 2x - 2x - 6

x + 9 = -6

Subtract 9 from both sides.

x + 9 - 9 = - 6 - 9

Combine

x = - 15
