Question

me ayudan porfis, no necesito para hoy :'(​

Answer 1

Respuesta:

Explicación paso a paso:

1-

2x+3x+5= 65

5x= 60

x= 60/5

x= 12

2-

y-3y - 6= 28

-2y= 34

y= 34/-2

y= -17

3-

15 - a +4a = -6

3a= -21

a= -21/3

a= -7

4-

m+14-2m= -8

-m = -22

m= 22

5-

4x + 6 = -x - 14

4x + x = -14 - 6

5x= -20

x= -20/5

x= -4

6-

-6x + 8 = 2x + 64

- 6x - 2x = 64 - 8

-8x = 56

x= 56/ -8

x= -7

Answer 2

Respuesta:

1)

$2x + 3x + 5 = 65 \\ 2x + 3x = 65 - 5 \\ 5x = 60 \\ x = 60 \div 5 \\ x = 12$

2)

$15 - a + 4a = - 6 \\ - a + 4a = - 6 - 15 \\ 3a = - 21 \\ a = - 21 \div 3 \\ a = - 7$

3)

$4x + 6 = - x - 14 \\ 4x + x = - 14 - 6 \\ 5x = - 20 \\ x = - 20 \div 5 \\ x = - 4$

4)

$y - 3y - 6 = 28 \\ y - 3y = 28 + 6 \\ - 2y = 34 \\ y = 34 \div ( - 2) \\ y = - 17$

5)

$m + 14 - 2m = - 8 \\ m - 2m = - 8 - 14 \\ - m = - 22 \\ m = - 22 \div ( - 1) \\ m = 22$

6)

$- 6x + 8 = 2x + 64 \\ - 6x - 2x = 64 - 8 \\ - 8x = 56 \\ x = 56 \div ( - 8) \\ x = - 7$
