Question
Solve the equation
Solve for x
x=−101
Alternative Form
x=−0.1
Evaluate
−6(−3x−1)+2=8x+7
Move the expression to the left side
−6(−3x−1)+2−(8x+7)=0
Calculate the sum or difference
More Steps
Evaluate
−6(−3x−1)+2−(8x+7)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−6(−3x−1)+2−8x−7
Subtract the numbers
−6(−3x−1)−5−8x
−6(−3x−1)−5−8x=0
Calculate
More Steps
Evaluate
−6(−3x−1)−5−8x
Expand the expression
More Steps
Calculate
−6(−3x−1)
Apply the distributive property
−6(−3x)−(−6×1)
Multiply the numbers
18x−(−6×1)
Any expression multiplied by 1 remains the same
18x−(−6)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
18x+6
18x+6−5−8x
Subtract the terms
More Steps
Evaluate
18x−8x
Collect like terms by calculating the sum or difference of their coefficients
(18−8)x
Subtract the numbers
10x
10x+6−5
Subtract the numbers
10x+1
10x+1=0
Move the constant to the right-hand side and change its sign
10x=0−1
Removing 0 doesn't change the value,so remove it from the expression
10x=−1
Divide both sides
1010x=10−1
Divide the numbers
x=10−1
Solution
x=−101
Alternative Form
x=−0.1
