Answer:
x = -18
Step-by-step explanation:
x - (-5)= - 23
you would do the opposite of -5 which is positive 5 and you would add 5 to the negative 5 to cancel out that -5 and add 5 to the -23 which gives you -18 so x = -18
Hope this helps!

Answer:
Step-by-step explanation:
Let the number be 'x'
Reciprocal = 
Cross multiply
(x² + 1) *2 = 5*x
2x² + 2 = 5x
2x² - 5x + 2 =0
Factorize the equation,
Sum = -5
Product = 4
Factors = -1 , -4
2x² - x - 4x + 2 = 0
x(2x - 1) - 2(2x - 1) = 0
(2x -1 )(x - 2) = 0
2x - 1 = 0 ; x -2 = 0
2x =1 ; x = 2
x = 1/2
Number = 2 , and its reciprocal = 1/2
