-4x-2-\left(-3x-5\right)=3
To find the opposite of 4x+2, find the opposite of each term.
-4x-2-\left(-3x\right)-\left(-5\right)=3
To find the opposite of -3x-5, find the opposite of each term.
-4x-2+3x-\left(-5\right)=3
The opposite of -3x is 3x.
-4x-2+3x+5=3
The opposite of -5 is 5.
-x-2+5=3
Combine -4x and 3x to get -x.
-x+3=3
Add -2 and 5 to get 3.
-x=3-3
Subtract 3 from both sides.
-x=0
Subtract 3 from 3 to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since -1 is not equal to 0, x must be equal to 0.
