2abx + by = 1ax + y = 2 indica el valor de x?

2abx + by = 1.

1

ax + y = 2 .

Ax = 2 - y.

2

reemplazando 2 en 1

2b(2 - y) + by = 1

4b - 2by + by = 1

4b - by = 1

b(4 - y) = 1.

B = 1 / (4 - y).

4 - y = 1 / b.

Y = 4 - 1 / b.

Y = (4b - 1) / b

de 2 despejando x x = (2 - y) / a

reemplazando el valor de y x = (2 - (4b - 1) / b) / a x = (2b - 4b + 1) / b / a x = ( - 2b + 1) / ab o también x = (1 - 2b) / ab.
