Please help me ​

Answer 1

Step-by-step explanation:

7x/4x-4/4x=3

7/4-1/x=3

7/4=3+1/x

7/4=(3x+1)/x

7/4x=3x+1

x-3x=1*4/7

-2x=4/7

x=4/7+2

x=(4+14)/7=18/7

Answer 2

Answer:

$x=-4/5$

Step-by-step explanation:

$7x/4x-4/4x=3$

$(7x-4)/4x=3$

$7x-4=3*4x$

$7x-4=12x$

$-4=12x-7x$

$-4=5x$

$-4/5=x$

$x=-4/5$
