Exercise 4 Page 252

Substitute 14 into the given equation and then simplify.

No

Practice makes perfect
We can determine whether 14 is a solution by substituting it into the equation and simplifying using the order of operations.
q/2 = 28
14/2 ? = 28
7 ≠ 28 *
Since both sides are not equal, 14 is not a solution.
