Exercise 11 Page 254

Substitute 36 into the given equation and then simplify.

No

Practice makes perfect
We can determine whether 36 is a solution by substituting it into the equation and simplifying using the order of operations.
n + 8 = 42
36 + 8 ? = 42
44 ≠ 42 *
Since both sides are not equal, 36 is not a solution.
