Answer 2

Solving the Equation 7x + 1 = 8

To solve the equation 7x + 1 = 8, we can follow these steps:

1. Isolate the Variable x: Subtract 1 from both sides of the equation to isolate the variable x. The equation becomes: 7x = 8 - 1

2. Simplify: Simplify the right-hand side of the equation. The equation becomes: 7x = 7

3. Solve for x: Divide both sides by 7 to solve for x. The solution is: x = 1

Finding the Opposite of the Root of the Equation

The opposite of the root of the equation x = 1 is -1.

Therefore, the number opposite to the root of the equation is -1.
