Exercise 20 Page 256

Substitute 4 into the given equation and then simplify.

No

Practice makes perfect
We can determine whether 4 is a solution by substituting it into the equation and simplifying using the order of operations.
m/4 = 16
4/4 ? = 16
1 ≠ 16 *
Since both sides are not equal, 4 is not a solution.
