Respuesta:
a= x=16.5
b= x=22.6
c= [tex]x=\frac{36}{5}[/tex]
d= [tex]x=\frac{41}{2}[/tex]
Explicación paso a paso:
1) x+7=23.5
x+7−7 = 23.5−7
x=16.5
Solución:
-----------------------------
2) x-4.6=18
x−4.6+4.6 = 18+4.6
x=22.6
--------------------------------
3) 5x=36
[tex]\frac{5x}{5}= \frac{36}{5}[/tex]
[tex]x=\frac{36}{5}[/tex]
----------------------------------
4) 2x+4=45
2x+4−4 = 45−4
2x=41
[tex]\frac{2x}{2}= \frac{41}{2}[/tex]
[tex]x=\frac{41}{2}[/tex]
