2 answers:
x + 2x - x - 1
- Substitute 2 for x into the expression.
(2) + 2(2) - (2) - 1
(2) + (4) - (2) - 1
- Solve from left to right.
- (2 + 4) - 2 - 1 = 6 - 2 - 1
6 - 2 - 1
- Solve from left to right.
- (6 - 2) - 1 = 4 - 1
4 - 1 = 3
<h3>Your answer is 3.</h3>
The Equation is
x + 2x - x - 1 = 0
The Value of x = 2 ,
Putting in Equation , we get
2 + (2 × 2) - 2 - 1 = 0
2 + 4 - 2 - 1 = 0
