Question

What is two less than 3 times a number is the same as the number plus 10

Answer 1

Two less than 3 times a number is:

3x - 2

The number plus ten is:

x + 10

If both are the same, we can write them as:

3x - 2 = x + 10                  / + 2 (both sides)
3x = x + 12                        / - x (both sides)
2x = 12                              / ÷ 2 (both sides)
x = 6
