Question

Me ayudarian resolver esta operaciones

Answer 1

2)

(x + 1)/(2x) + (2x + 3)/(3x) =

3(x + 1)/(6x) + 2(2x + 3)/(6x) =

(3x + 3)/(6x) + (4x + 6)/(6x) =

(3x + 3 + 4x + 6)/(6x) =

(7x + 9)/(6x)

4)

(2x + 5)/(6x) - (x + 6)/(4x²) =

4x(2x + 5)/(24x²) - 6(x + 6)/(24x²) =

(8x² + 20x)/(24x²) - (6x + 36)/(24x²) =

(8x² + 20x - 6x - 36)/(24x²) =

(8x² + 14x - 36)/(24x²) =

(4x² + 7x - 18)/(12x²)
