Question

3/4x+1/x+1/5=7/4 solve the equation and verify

Answer 1

Answer:

Step-by-step explanation:

12+4+4=28x+7x+35

20=35x+35

35x=35-20

35x=15

x=15/35

x=3/7

Answer 2

Answer:

3/4x+1/x+1/5=7/4

3/4x+1/x=7/4-1/5

(3x+4x)/(4x.x)=31/20

20*(3x+4x)=31*4x^2

60x+80x=124x^2

140x=124x^2

140x-124x^2=0

4x(35-31x)=0

=> 4x=0 or 35-31x=0

x=0        or  31x=35

                      x=35/31

=> x=0 or x=35/31
