Question
Solve the equation
Solve for x
x=−3
Evaluate
2(x+1)−(x−1)=0
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
2(x+1)−x+1=0
Calculate the sum or difference
More Steps
Evaluate
2(x+1)−x+1
Expand the expression
More Steps
Calculate
2(x+1)
Apply the distributive property
2x+2×1
Any expression multiplied by 1 remains the same
