numerator = x
denominator = x+8
so, numerator is increased by 17 and denominator decreased by 1.
x+17 / x+8-1 = 3/2
x+17 / x+7 = 3/2
(now, cross multiply)
3(x+7) = 2(x+17)
3x + (3*7) = 2x + (2*17)
3x + 21 = 2x + 34
3x - 2x = 34 - 21
x = 13
therefore, the rational number is 13/20
The number that should be added to both sides is 16 because its half of b, which is then squared. You then get (x+4)^2=20, which you then square root both sides and get x+4=+-20 and then subtract the 4 to get x=-4+-20
Answer:
Make the variables different then just try random numbers

Answer:
(17y/8) - 101 or (17y - 808) / 8
Step-by-step explanation:
Please enclose the fractional coefficient 1/8 inside paretheses:
(1/8)y + 17 + 2y - 118.
Now combine like terms. (1/8)y + 2y comes to (1/8)y + 16y/8 = (17/8)y.
We thus have (17/8)y + 17 - 118. Leaving (17/8)y alone, evaluate 17 - 118:
(17y/8) - 101
You could leave your answer in this form, or combine the terms using the LCD 8:
17y - 808
