2x - 1 = 3
First, we need to get the variable (x) on one side by itself. Add 1 to each side.
[tex]2x = 3 + 1[/tex]
Second, add 3 + 1 to get 4.
[tex]2x = 4[/tex]
Third, divide each side by 2. This will complete our goal of getting the variable (x) by itself.
[tex]x = \frac{4}{2} [/tex]
Fourth, our last step is to simplify the fraction. In simpler words, what times 2 equals 4? (2 × 2 = 4), so we can simplify it to 2.
[tex]x = 2[/tex]
Answer: [tex]\fbox {x = 2}[/tex]
