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