Question
Solve the equation
x=2
Evaluate
12−3(x−1)=9
Move the expression to the left side
12−3(x−1)−9=0
Subtract the numbers
3−3(x−1)=0
Calculate
More Steps

Evaluate
3−3(x−1)
Expand the expression
More Steps

Calculate
−3(x−1)
Apply the distributive property
−3x−(−3×1)
Any expression multiplied by 1 remains the same
−3x−(−3)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−3x+3
3−3x+3
Add the numbers
6−3x
6−3x=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
Change the signs on both sides of the equation
3x=6
Divide both sides
33x=36
Divide the numbers
x=36
