Exercise 29 Page 256

Use the Addition Property of Equality to eliminate the subtraction.

f= 46

Practice makes perfect

To solve the equation, we have to isolate f on one side. Using the Addition Property of Equality, we will add 27 to both sides of the equation. This will eliminate the subtraction and isolate f.

f-27=19
AddEqn

LHS+27=RHS+27

f-27+27=19+27
AddTerms

f=46

To check that this solution is correct, let's substitute f= 46 into the original equation and simplify.

f - 27 = 19
Substitute

f= 46

46 - 27? = 19
SubTerm

Subtract term

19 = 19 ✓

Since the left-hand side and right-hand side are equal, f= 46 is the correct solution.
