Question

7 times a number equals 3 less than 5 times that number. what is the number?

Answer 1

First the equation would look like this:

7n = 5n - 3

7n - 5n = 5n - 5n - 3   -Subtract 5n from both sides.  Which gives you...

2n = -3      

2n/2 = -3/2          -Divide both sides by 2

n = -1.5

Hope this helps!
