Question

1) Resolver las siguientes ecuaciones

A_ 3X + 4 – 1 = 9

B_ 4 X – 5 = 2 X + 7 – 4

C _ 2 ( X – 3 ) = X + 7

D_ 5 ( X + 2 ) = 3 ( X – 1 ) – 1

E_ 3 ( 2X – 1 ) = 4 ( X – 2 ) + X

F_ 3/2 X – 4 = 5

​

Answer 1

Respuesta:

A 3x+4-1=9

3x=9-4+1

3x=6

x=6:3

x= 2

B 4x-5=2x+7-4

4x-2x=7-4+5

2x= 8

x=8:2

x=4

C 2(X-3)=X+7

2x-6=x+7

2x-x=7+6

x=13

D 5(X+2)=3(X-1)-1

5X+10=3X-3-1

5X-3X=-4-10

2X=-14

X=14:2

X=7

E 3(2X-1)=4(X-2)+X

5X-3=4X-8+X

5X-5X=-8+3

0X=-5

F 3/2X-4=5

3/2X=5+4

3/2X=9

X=9:3/2

X=6
