|8|≠7

Answer 2

Checking if 7 is a Root of the Equation |x + 1| = 7

To determine if 7 is a root of the equation |x + 1| = 7, we can solve the equation and check if x = 7 satisfies it.

The equation |x + 1| = 7 can be split into two separate equations: 1. x + 1 = 7 2. -(x + 1) = 7

Solving these equations will give us the possible values of x.

1. For x + 1 = 7: - x = 7 - 1 - x = 6

2. For -(x + 1) = 7: - -(x + 1) = 7 - -x - 1 = 7 - -x = 7 + 1 - -x = 8 - x = -8

Therefore, the possible values of x that satisfy the equation |x + 1| = 7 are x = 6 and x = -8. Since 7 is not a root of the equation |x + 1| = 7, it does not satisfy the equation.

So, 7 is not a root of the equation |x + 1| = 7. This is based on the solutions obtained for the equation.
