I will assume you may mean this...
(2X + 3)/(X + 7) = 5/3
multiply through by (X + 7) ( distribute the 5/3 to this )
2X + 3 = (5/3)X + 35/3
(1/3)X + 3 = 35/3
(1/3)X = 26/3
X = 26
====== The check shows 5/3, which is correct, but this … Read more
Let the number be x
((2x+3)/x) +7= 5/3
take l.c.m
therefore (2x+3+7x)/x=5/3
(9x+3)=5x/3
3(9x+3)=5x
27x+9=5x
27x+9-5x=0
22x=-9
x= -9/22
so the number is -9/22
