Answer:
x=3/8
Explanation:
Multiplique dentro del paréntesis por
-1
/
2
.
Después de haber multiplicado le ecuación le quedará así
3x
+
5
/
4
+
1
=
9x
.
Ahora vamos a calcular la suma de la ecuación y quedará a
3x
+
9
/
4
=
9x
.
Después vamos a multiplicar ambos lados de la ecuación por
4
y quedará a
12x
+
9
=
36x
.
Luego vamos a mover la constante ( que es
9
) al lado derecho y cambié su signo y quedará a
12x
=
36x
-
9
.
Después vamos agrupar los términos semejantes ( en este caso
x
) y quedará a
-24x
=
-9
.
Finalmente vamos a dividir ambos lados de la ecuación entre
-24
y la respuesta nos quedará a
x
=
3
/
8
.
