Question

Resolva as equações a seguir
A 18x-43=65
B 23x-1=14-17x
C 10y-5(1+y) =3(2y-2)-20
D 30-20+2x=10
E 4x-x-x=24-12
Me ajudem por favor

Answer 1

a)18x=65+43
18x=108
x=108/18
X=6

b)23x+17x=14+1
40x=15
x=15/40

c)10y-5-5y=6y-6-20
10y-5y-6y=-6-20+5
-1y=-21 .(-1)
y=21


d)2x=10-30+20
2x=0
x=0/2
x=0


e)4x-2x=24-12
2x=12
x=12/2
x=6
