Respuesta:
r = 2/5 y h = 4
Explicación paso a paso:
5r + 3 = 5
5r = 5 - 3
5r = 2
r = 2/5 (en decimales es 0.4)
7h - 4 = 3h + 12
7h - 3h = 12 + 4
4h = 16
h = 16/4
h = 4
Hola las respuestas son :
A) 5r+3=5
[tex]5r + 3 - 3 = 5 - 3 \\+3 - 3 = 0 \\5 - 3 = 2 \\5r = 2 \\\\\frac{5r}{5} = \frac{2}{5} \\\\r= \frac{2}{5} R//[/tex]
B) 7h-4=3h+12
[tex]7h -4 + 4 = 3h +12 + 4 \\7h = 3h + 16 \\7h -3h = 3h + 16 - 3h \\4h = 16 \\\\\frac{4h}{4 } = \frac{16}{4} \\ h = 4 R//[/tex]
Espero te sirva saludos suerte
