(1/x) + 1/(x-1) = (3/2)
{(x-1)+x}/x(x-1)=3/2
(2x-1/x^2-x)=3/2
2(2x-1)=3(x^2-x)
4x-2=3x^2-3x
3x^2-3x-4x+2=0
3x^2-7x+2=0
3x^2-6x-x+2=0
3x(x-2)-1(x-2)=0
(x-2)(3x-1)=0
=>x-2=0,3x-1=0
=>x=2,x=1/3

Remember how to add fractions with different denominators. You find the common denominator, convert, and add the numerators. If the two denominators have no factors in common, then the lowest common denominator is simply the product of the two denominators.



Now you have a simple proportion. Cross-multiply, collect like terms, and then solve the resulting quadratic. Said quadratic is factorable and therefore has two real roots.

My calculator said it, I believe it, that settles it

%281%2Fx%29%2B1%2F%28x-1%29=%283%2F2%29 Multiply through by x.
.
1%2Bx%2F%28x-1%29=%283%2F2%29%28x%29 Multiply through by (x-1)
%28x-1%29%2Bx=%283%2F2%29%28x%29%28x-1%29 Multiply each side by (2/3).
%284%2F3%29x-%282%2F3%29=x%5E2-x Subtract (4/3)x from each side.
%28-2%2F3%29=x%5E2-%287%2F3%29x Add 2/3 to each side
0=x%5E2-%287%2F3%29x%2B%282%2F3%29 Multiply by 3.
0=3x%5E2-7x%2B2
0=%28x-2%29%283x-1%29
x-2=0 OR 3x-1=0
x=2 OR 3x=1
x=2 OR x=%281%2F3%29

1%2Fx+%2B+1%2F%28x+-+1%29+=+3%2F2
2(x - 1) + 2x = 3x(x - 1) ------ Multiplying through by LCD: 2x(x - 1)
2x+-+1+%2B+2x+=+3x%5E2+-+3x
4x+-+1+=+3x%5E2+-+3x
3x%5E2+-+3x+-+4x+%2B+1+=+0
3x%5E2+-+7x+%2B+1+=+0
(3x - 1)(x - 2) = 0 ------ Factoring trinomial to determine solutions
3x - 1 = 0 OR x - 2 = 0
highlight_green%28x+=+1%2F3%29 OR highlight_green%28x+=+2%29
Both satisfy the original equation so both are solutions.
