Exercise 9 Page 276

Substitute 7 into the given equation and then simplify.

Yes

Practice makes perfect
We can determine whether x=7 is a solution by substituting it into the equation and simplifying using the order of operations.
x+9=16
Substitute

x= 7

7+9? =16
AddTerms

Add terms

16=16
Since both sides are equal, 7 is a solution.
