Question

The sum of three times a number and 8 is –22. What is the number?

Answer 1

3x + 8 = -22
      -8         -8
3x = -30

x = -30/3  = -10

Correct choice is 1).

Answer 2

Let the number = X

3 times the number = 3x

So we have 3x +8 = -22

Subtract 8 from each side:
3x = -30

Divide both sides by 3:
x=-30/3
X = -10

The answer is 1.) -10
