How to solve the equation x-20 + 1 / 3x = 80?

How to solve the equation x-20 + 1 / 3x = 80?


x-20+1/3x=80
3x-60+x=240
4x=300
x=75



Solution equation: 34 + x = 78.6


x=78.6-34
x=44.6



2.2x-x = 9.6


2.2x-x = 9.6 leads to 1.2x = 9.6 leads to x = 8



Solving equation 2 ^ (- 2x-14) = (1 / 16) ^ (x ^ 2 + 2)


2^(-2x-14)=(1/2^4)^(x^2+2)
2^(-2x-14)=[2^(-4)]^(x^2+2)
2^(-2x-14)=2^(-4x²-8)
-2x-14=-4x²-8
2x²-x-3=0
(2x-3)(x+1)=0
x=3/2,x=-1
