$\large \bold{x + 1 = 9}$

$\large \bold{x = 9 - 1}$

$\large \bold{x = \red{8}}$

Answer 2

Explanation:

Equation: x + 1 = 9

Solving Steps:

x + 1 = 9                 (subtract both sides by 1)

x + 1 - 1 = 9 - 1        (simplify the following)

x = 8

Then check for solution:

x + 1 = 9

                         [insert x = 8]

8 + 1 = 9

9  =  9

As both sides are equal, the statement is true.
