Exercise 1 Page 440

Use the Subtraction Property of Equality to eliminate the addition.

n=2

Practice makes perfect

To solve the equation, we have to isolate n on one side. Using the Subtraction Property of Equality, we can subtract 6 from both sides of the equation. This will eliminate addition on the left-hand side and isolate n.

n+6=8

SubEqn

LHS- 6=RHS- 6

n+6- 6=8- 6

SubTerms

Subtract terms

n=2

To check that this solution is correct, let's substitute n=2 into the original equation and simplify.

n+6=8

Substitute

n= 2

2+6? =8
