Question
Simplify the expression
2x−1
Evaluate
(x×1)−(1−x)
Any expression multiplied by 1 remains the same
x−(1−x)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
x−1+x
Solution
More Steps

Evaluate
x+x
Collect like terms by calculating the sum or difference of their coefficients
(1+1)x
Add the numbers
2x
2x−1

Find the roots
x=21
Alternative Form
x=0.5
Evaluate
(x×1)−(1−x)
To find the roots of the expression,set the expression equal to 0
(x×1)−(1−x)=0
Any expression multiplied by 1 remains the same
x−(1−x)=0

2x−1
2x−1=0
Move the constant to the right-hand side and change its sign
2x=0+1
Removing 0 doesn't change the value,so remove it from the expression
2x=1
Divide both sides
22x=21
Solution
x=21
