Question

Eight times a number equals 18 less than 2 times the number. find the number

Answer 1

n = -3

Step-by-step explanation

We have that eight times a number equals 18 less than 2 times the number.

Let the number be n.

We can derive the equation from the statement as:

8 * n = 2 * n - 18

=> 8n = 2n - 18

To find the number, we have to find the value of n.

To do that, collect like terms:

8n - 2n = -18

6n = -18

Divide through by 6:

n = -18/6

n = -3

That is the number.
