Question

Solve for rational equations

Answer 1

x=8

Explanation:

`(7)/(8) - (1)/(x) = (3)/(4)`

`8x( (7)/(8) - (1)/(x) ) = 8x( (3)/(4) )`

`7x - 8 = 6x`

`7x - 6x = 8`

`x = 8`

Answer 2

x= 8

Explanation:

drag 7/8 to the other side of equality

now,

-1/x=3/4-7/8

now taking lcm to the right side of equation

-1/x= 6-7/8

-1/x=-1/8

multipky by -1 on both sides of equation

1/x=1/8

now take reciprocal

x=8
