Explicación paso a paso:
[tex]\frac{1}{x}+ \frac{3}{y+1} =\frac{5}{4}[/tex] ⇒ se multiplica todo x 4
[tex]\frac{4}{x}+ \frac{12}{y+1} =\frac{20}{4}[/tex]
[tex]\frac{4}{x} +\frac{7}{y+1}= \frac{15}{4}[/tex] ↓↓↓ se restan
[tex]\frac{5}{y+1} =\frac{5}{4}[/tex]
y + 1 = 4
Se reemplaza: [tex]\frac{4}{x} +\frac{7}{4} =\frac{15}{4} \\\\\frac{4}{x}= \frac{8}{4} =2\\\\x=2[/tex]

⇒ y = 3
Se reemplaza: [tex]\frac{4}{x} +\frac{7}{4} =\frac{15}{4} \\\\\frac{4}{x}= \frac{8}{4} =2\\\\x=2[/tex]
∴ x = 2, y = 3
