The value of x from the given expression is negative start fraction 17 over 3 end fraction
How to solve proportions?
The given proportion is as follows;
x+1/x-1 = 14/20
we have to cross multiply
20(x + 1) = 14(x - 1)
open the brackets
20x + 20 = 14x - 14
subtract 14x from both sides
20x - 14x + 20 = 14x - 14x - 14
6x + 20 = -14
subtract 20 from both sides
6x + 20 - 20 = -14 - 20
6x = -34
divide both sides by 6
6x / 6 = -34 / 6
x = - 17 / 3
Hence the value of x from the given expression is negative start fraction 17 over 3 end fraction
