7+1=8

8/2=4

Answer 2

To find the root of the equation 2x - 1 = 7, we need to isolate the variable x on one side of the equation. Here's how you can solve it:

2x - 1 = 7

First, let's add 1 to both sides of the equation to eliminate the constant term on the left side:

2x - 1 + 1 = 7 + 1

Simplifying the equation:

2x = 8

Now, to isolate x, we need to divide both sides of the equation by 2:

(2x)/2 = 8/2

Simplifying further:

x = 4

Therefore, the root of the equation 2x - 1 = 7 is x = 4.
