Seven more than three times a number is 44. What is that number?

Answer 1

Select a number equal to x. This number x is three times its value, or 3x. If you want 7 more of this number than you are subtracting 7 from this number. The final answer is 44.

Therefore the equation is 3x - 7 = 44.

We want to isolate x. We need to move the 7 to the right side of the equation, so we add +7 to both sides of the equation.

3x - 7 (+7) = 44 + 7

3x = 51

Now multiply both sides of the equation by 1/3 to isolate x.

3x * 1/3 = 51 * 1/3

x = 17

Check your work by substituting x = 17 into the equation:

3(17) - 7 = 44

51 -7 = 44

Therefore the number x = 17.
