Question
Solve the equation
x=2
Evaluate
x−2=2x−4(x−1)
Move the expression to the left side
x−2−(2x−4(x−1))=0
Subtract the terms
More Steps
Evaluate
x−2−(2x−4(x−1))
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−2−2x+4(x−1)
Subtract the terms
More Steps
Evaluate
x−2x
Collect like terms by calculating the sum or difference of their coefficients
(1−2)x
Subtract the numbers
−x
−x−2+4(x−1)
−x−2+4(x−1)=0
Calculate the sum or difference
More Steps
Evaluate
−x−2+4(x−1)
Expand the expression
More Steps
Calculate
4(x−1)
Apply the distributive property
4x−4×1
Any expression multiplied by 1 remains the same
4x−4
−x−2+4x−4
Add the terms

Evaluate
−x+4x
Collect like terms by calculating the sum or difference of their coefficients
(−1+4)x
Add the numbers
3x
3x−2−4
Subtract the numbers
3x−6
3x−6=0
Move the constant to the right-hand side and change its sign
3x=0+6
Removing 0 doesn't change the value,so remove it from the expression
3x=6
Divide both sides
33x=36
Divide the numbers
x=36
