Question

1) 3X + 4( 2 – X) = 4 X + 5


2) 8Y + 2( Y – 4) = 8Y + 12


3) –2( 3w + 6) – ( 4w – 3) = 21


4) - 4( 2 Z – 6) = - 3(Z – 4) + Z


5) 8 – 3( 2 a – 4 ) = 5 + 3a - 4


6) 4( 2X – 2) – 3( X + 7) = -4


7) 4,7X – 3.6( X – 1) = 4.9


8) 5( m + 3) – m = -( 4m – 6) + 1

Answer 2

Respuesta:

1) 3x + 8-4x=4x+5

-1x+8=4x+5

-1x+8-4x=4x+5-4x

-5x+8=5

-5x+8-8=5-8

-5x=-3

(-1) -5x=(-1) -3

5x=3

5x/5 =3/5

x= 0.6

2) 8y+2y-8=8y+12

10y-8+8=8y+12+8

10y=8y+20

10y-8y=8y+20-8y

2y=20

2y/2=20/2

y=10

3) -6w+12-4w+3=21

-10w+15=21

-10w+15-15=21-15

-10w=6

(-1) -10w=(-1) 6

10w=-6

10w/10=-6/10

w=-0.6

4) -8z+24=-3z+12+z

-8z+24=-2z+12

-8z+24+2z=-2z+12+2z

-6z+24=12

-6z+24-24=12-24

-6z=-12

(-1) -6z=(-1) -12

6z=12

6z/6=12/6

z=2

5) 8-6a+12=5+3a-4

20-6a=1+3a

20-6a-3a=1+3a-3a

20-9a=1

20-9a-20=1-20

-9a= -19

(-1) -9a= (-1) -19

9a=19

9a/9=19/9

a= 2.11

6)4( 2X – 2) – 3( X + 7) = -4

8x-8-3x-21=-4

5x-29=-4

5x-29+29=-4+29

5x=25

5x/5=25/5

x= 5

7) 4.7x-3.6x+3.6=4.9

1.1x+3.6=4.9

1.1x+3.6-3.6=4.9-3.6

1.1x=1.3

1.1x/1.1=1.3/1.1

x= 1.18

8) 5m+15-m=-4m+6+1

4m+15=-4m +7

4m+15-15=-4m+7-15

4m=-4m-8

4m+4m=-4m-8+4m

8m=-8

8m/8=-8/8

m= -1
