Evaluate
x−1=0
Move the constant to the right side
x=0+1
Removing 0 doesn't change the value,so remove it from the expression
x=1
{x=1x+1=0
Calculate

Evaluate
x+1=0
Move the constant to the right side
x=0−1
Removing 0 doesn't change the value,so remove it from the expression
x=−1
{x=1x=−1
Find the intersection
x∈(−∞,−1)∪(−1,1)∪(1,+∞)
x−16+x+15=x−16,x∈(−∞,−1)∪(−1,1)∪(1,+∞)
Multiply both sides of the equation by LCD
(x−16+x+15)(x−1)(x+1)=x−16×(x−1)(x+1)
Simplify the equation
More Steps
Evaluate
(x−16+x+15)(x−1)(x+1)
Apply the distributive property
x−16×(x−1)(x+1)+x+15×(x−1)(x+1)
