Evaluate
−ϕ−ϕ
Collect like terms by calculating the sum or difference of their coefficients
(−1−1)ϕ
Subtract the numbers
−2ϕ
π−2ϕ−1
π−2ϕ−1−π=0
Since two opposites add up to 0,remove them form the expression
−2ϕ−1=0
Move the constant to the right-hand side and change its sign
−2ϕ=0+1
Removing 0 doesn't change the value,so remove it from the expression
−2ϕ=1
Change the signs on both sides of the equation
2ϕ=−1
Divide both sides
22ϕ=2−1
Divide the numbers
ϕ=2−1
Solution
ϕ=−21
Alternative Form
