Question
Solve the equation
x=−1
Evaluate
−9(x−1)−15=3
Move the expression to the left side
−9(x−1)−15−3=0
Subtract the numbers
−9(x−1)−18=0
Calculate
More Steps

Evaluate
−9(x−1)−18
Expand the expression
More Steps

Calculate
−9(x−1)
Apply the distributive property
−9x−(−9×1)
Any expression multiplied by 1 remains the same
−9x−(−9)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−9x+9
−9x+9−18
Subtract the numbers
−9x−9
−9x−9=0
Move the constant to the right-hand side and change its sign
−9x=0+9
Removing 0 doesn't change the value,so remove it from the expression
−9x=9
Change the signs on both sides of the equation
9x=−9
Divide both sides
99x=9−9
Divide the numbers
x=9−9
