we must solve this equation:
[tex]\frac{7}{20}+x=\frac{19}{20}[/tex]First, we must move 7/20 to the right hand side as -7/20. It yields,
[tex]x=\frac{19}{20}-\frac{7}{20}[/tex]and now we can substract these fractions,
[tex]\begin{gathered} x=\frac{19-7}{20} \\ x=\frac{12}{20} \end{gathered}[/tex]since 12=4*3 and 20=4*5, we can rewrite this result as
[tex]\begin{gathered} x=\frac{4\cdot3}{4\cdot5} \\ \end{gathered}[/tex]and finally, the answer is x=3/5
