Question

Solve the equation; 2x-1=3

Answer 1

2x-1=3
+1 +1
2x=4
divide by 2
x=2

Answer 2

2x - 1 = 3

First, we need to get the variable (x) on one side by itself. Add 1 to each side.

`2x = 3 + 1`

Second, add 3 + 1 to get 4.

`2x = 4`

Third, divide each side by 2. This will complete our goal of getting the variable (x) by itself.

`x = (4)/(2)`

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.

`x = 2`

Answer:
`\fbox {x = 2}`
