Answer
$13x-9$
Work Step by Step
Substract $(3x+1)$ from the sum of $(4x-3)$ and $(12x-5)$
This expression can be translated to:
$[(4x-3)+(12x-5)]-(3x+1)$
First, evaluate the sum inside the brackets:
$[(4+12)x-(5+3)]-(3x+1)=(16x-8)-(3x+1)=...$
Remove both parentheses. To remove the second one, change the sign of every term inside it:
$...=16x-8-3x-1=...$
Simplify by combining like terms:
$...=(16-3)x-(8+1)=13x-9$
