Question
Solve the equation
n=−71
Alternative Form
n=−0.1˙42857˙
Evaluate
n−1=n×8
Use the commutative property to reorder the terms
n−1=8n
Move the variable to the left side
n−1−8n=0
Subtract the terms
More Steps
Evaluate
n−8n
Collect like terms by calculating the sum or difference of their coefficients
(1−8)n
Subtract the numbers
−7n
−7n−1=0
Move the constant to the right side
−7n=0+1
Removing 0 doesn't change the value,so remove it from the expression
−7n=1
Change the signs on both sides of the equation
7n=−1
Divide both sides
77n=7−1
Divide the numbers
n=7−1
