Solve the equation
x=3
Evaluate
5−2(x−1)=4−x
Move the expression to the left side
5−2(x−1)−(4−x)=0
Subtract the terms
More Steps
Evaluate
5−2(x−1)−(4−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
5−2(x−1)−4+x
Subtract the numbers
1−2(x−1)+x
1−2(x−1)+x=0
Calculate the sum or difference
More Steps
Evaluate
1−2(x−1)+x
Expand the expression
More Steps
Calculate
−2(x−1)
Apply the distributive property
−2x−(−2×1)
Any expression multiplied by 1 remains the same
−2x−(−2)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−2x+2
1−2x+2+x
Add the numbers
3−2x+x
Add the terms
More Steps
Evaluate
−2x+x
Collect like terms by calculating the sum or difference of their coefficients
(−2+1)x
Add the numbers
−x
3−x
3−x=0
Move the constant to the right-hand side and change its sign
−x=0−3
Removing 0 doesn't change the value,so remove it from the expression
−x=−3
Solution
x=3
