150 7x 1 Solution7x87x58 take 1x as common 1x78758 1x778758

Solution

(7/x)+(8/(7x))=58

take 1/x as common

(1/x)[7+(8/7)]=58

(1/x)[((7*7)+8)/7)]=58

(1/x)[(49+8)/7]=58

(1/x)[57/7]=58

x=57/(7*58)

x=57/406

====================================

4=(v/(7))

squaring on both sides

4²=((v/(7)))²

16=v/(7)

v=16*7

v=112

=======================================

[3/(x-4)] +5 =9

subtract 5 on both sides

[3/(x-4)] +5 -5=9-5

[3/(x-4)] =4

x-4 =(3/4)

x=4+(3/4)

x=((4*4)+3)/4

x=19/4
