Answer 1

7(x+$\dfrac{1}{5}$)=1$\dfrac{3}{4}$

7x+$\dfrac{7}{5}$=$\dfrac{7}{4}$

7x=$\dfrac{7}{4}$-$\dfrac{7}{5}$

7x=$\dfrac{35-28}{20}$

7x=$\dfrac{7}{20}$

x=$\dfrac{\frac{7}{20}}{7}$=$\dfrac{7}{20}$·$\dfrac{1}{7}$=$\dfrac{1}{20}$

Answer 2

7(5x+1/5)=7/4

35x+7/5=7/4

108x+28=35

140x=35 - 28

140x=7

x=7/140 

x=1/20
