7. Subtract Linear Expressions
Sign In
To find the additive inverse of a linear expression, you can multiply each term of the expression by -1.
-1 12x +1 12
First, let's find the additive inverse of the linear expression within the second set of parentheses. To do so, we can distribute -1 into the second set of parentheses. When we do so, we multiply each term of that linear expression by -1.
Distribute -1
(- a)b = - ab
a+(- b)=a-b
Commutative Property of Addition
a/b=a * 2/b * 2
