Answer 1

First, let's declare our variables.

x = variable 1

x + 1 = variable 2

x + 2 = variable 3

Now, let's create our expression.

x + x+1 + x+2 = 147

Let's add like terms

3x + 3 = 147

Subtract 3 from both sides

3x = 144

Divide both sides by 3

x = 48

x + 1 = 48 + 1 = 49

x + 2 = 48 + 2 = 50
