Question
Solve the equation
x=12
Evaluate
(x−1)+x+(x+1)=36
Simplify
More Steps
Evaluate
(x−1)+x+(x+1)
Remove the parentheses
x−1+x+(x+1)
Remove the parentheses
x−1+x+x+1
Add the terms
More Steps
Evaluate
x+x+x
Collect like terms by calculating the sum or difference of their coefficients
(1+1+1)x
Add the numbers
3x
3x−1+1
Since two opposites add up to 0,remove them form the expression
3x
3x=36
Divide both sides
33x=336
Divide the numbers
x=336
