\frac{1}{2} + \frac{1}{x} = 2 \cdot 0.9876883405951378
Evaluate trigonometric functions in the problem
2x\times \frac{1}{2}+2=2\times 0.9876883405951378\times 2x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 2x, the least common multiple of 2,x.
x+2=2\times 0.9876883405951378\times 2x
Cancel out 2 and 2.
x+2=1.9753766811902756\times 2x
Multiply 2 and 0.9876883405951378 to get 1.9753766811902756.
x+2=3.9507533623805512x
Multiply 1.9753766811902756 and 2 to get 3.9507533623805512.
x+2-3.9507533623805512x=0
Subtract 3.9507533623805512x from both sides.
-2.9507533623805512x+2=0
Combine x and -3.9507533623805512x to get -2.9507533623805512x.
-2.9507533623805512x=-2
Subtract 2 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-2}{-2.9507533623805512}
Divide both sides by -2.9507533623805512.
x=\frac{-20000000000000000}{-29507533623805512}
