Question

1- x-4=2x-8
2- 6+2x=x+18
3- 3x-8=-x+10
4- -x+18=x-12
5- x-10=4x-19​

(con procedimiento)

Answer 1

Respuesta:

1) X - 4 = 2X - 8

X - 2X = -8 + 4

X = -4

2) 6 + 2X = X + 18

2X - X = 18 -6

X = 12

3) 3X - 8 = X + 10

3X - X = 10 + 8

2X = 18

X = 18

2

X = 9

4) -X + 18 = X -12

-X - X = -12 - 18

-2X = -30

X = -30

- 2

X = 15

5) X - 10 = 4X -19

X - 4X = - 19 + 10

- 3X = -9

X = -9

-3

X = 3

Answer 2

×-4=2×-8

×-2×=-8+4

(-1)-×=-4

×=4

6+2×=×+18

2×-×=18-6

×=12

3×-8=-×+10

3×+×=10+8

4×=18

×=18/4 Simplificamos

×=9/2

-×+18=×-12

-×-×=-12-18

-2×=-30

×=-30/-2

×=15

×-10=4×-19

×-4×=-19+10

-3×=-9

×=-9/-3

×=3
