The sum of ( x + ) + ( x - ) is x +
Step-by-step explanation:
To add or subtract 2 fractions, they must have same denominators, if they not do that
∵ ( x + ) + ( x - )
- Let us start with adding the like terms
∴ ( x + ) + ( x - ) = (
∵ ( x + x ) have same denominators, then we can add them
∴ ( x + x ) = x
∵ ( - ) do not have the same denominators, then we must find
LCM of 8 and 4
- The LCM of 8 and 4 is 8 because 8 is the first common multiple
of 8 and 4
∵ LCM of 8 and 4 is 8
- Divide 8 by the denominator 4
∵ 8 ÷ 4 = 2
- Multiply the numerator of the fraction by 2
∴
∴ ( - ) = ( - ) =
∴ ( x + ) + ( x - ) = x +
