Question

2)Resolva as equações a seguir:

A)18x-43=65
B)23x-16=14-17x
C)10y-5(1+y)=3(2y-2)-20
D)X(X+4)+X(x+2)=2x2+12
E)(x-5)/10+(1-2x)/5=(3x)/4
F)4x(x+6)-x2=5x2

​

Answer 1

A)18x-43=65

18x=65+43

18x=108

x= 108÷18

x=06

B)23x-16=14-17x

23x+17x=14+16

40x=30

x=30÷40

x= 0,75

C)10y-5(1+y)=3(2y-2)-20

D)X(X+4)+X(x+2)=2x2+12

E)(x-5)/10+(1-2x)/5=(3x)/4

F)4x(x+6)-x2=5x2
