Respuesta :

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

lets all multipled by 28
4 = 21x - 28
21x = 4 + 28
21x = 32
   x = 32/21
   x = 1 9/21 or  x = 1  3/7
Hi there, first we flip the equation to 3/4x-1=1/7, Now, we add 1 to both sides which makes it 3/4x=8/7. Finally, we multiply both sides by 4/3, now, 4/3*3/4x=4/3*8/7=32/21. Therefore, x=32/21
