Question

me ayudan con estas operaciones plis (corona)

(1)-3x+40=10
(2)-x-8=0
(3)-9x-35=10
(4)-4x+6=-30
(5)8x-18=30
(6)-x-6=3
(7)3x-26=10
(8)4x-8=8​

Answer 1

- 3x + 40 = 10

- 3x = 10 - 40

- 3x = - 30

3x = 30

x = 30 / 3

(x = 10)

- 1x - 8 = 0

- 1x = 0 + 8

- 1x = 8

(x = - 8)

- 9x - 35 = 10

- 9x = 10 + 35

- 9x = 45

- x = 45 / 9

- x = 5

(x = - 5)

- 4x + 6 = - 30

- 4x = - 30 - 6

- 4x = - 36

4x = 36

x = 36 / 4

(x = 9)

8x - 18 = 30

8x = 30 + 18

8x = 48

x = 48 / 8

(x = 6)

- 1x - 6 = 3

- 1x = 3 + 6

- 1x = 9

(x = - 9)

3x - 26 = 10

3x = 10 + 26

3x = 36

x = 36 / 3

(x = 12)

4x - 8 = 8

4x = 8 + 8

4x = 16

x = 16 / 4

(x = 4)
