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.
5x-2
Distribute -1
(- a)b = - ab
a+(- b)=a-b
( 9x+ 5)+( - 4x - 3) In this case, we have two x-terms and two constants. Let's arrange the like terms in columns. Then, let's perform the addition. 9 x +5& (+) -4 x -3& 5 x +2& Therefore, we get the following result. (9x+5)-(4x+3) = 5x-2
