Hola!

C :

1)

6(2 + 3x) + 3(x - 4) = 63

12 + 18x + 3x - 12 = 63

21x - = 63

21x = 63

x = 63 / 21

x = 3

2)

5(x + 3) - 11 = 2x + 19

5x + 15 - 11 = 2x + 19

5x - 2x = 19 - 4

3x = 15

x = 15 / 3

x = 5

3)

4x + 1 + 2.

(5 + x) = x + 71

4x + 1 + 10 + 2x = x + 71

6x + 11 = x + 71

6x - x = 71 - 11

5x = 60

x = 60 / 5

x = 12

4)

x ^ 2 - 5 = 59

x ^ 2 = 59 + 5

x ^ 2 = 64

x = √64

x = 8

5)

3x ^ 2 = 27

x ^ 2 = 27 / 3

x ^ 2 = 9

x = √9

x = 3

6)

x ^ 3 + 75 = 200

x ^ 3 = 200 - 75

x ^ 3 = 125

x = 3 * √125

x = 5

7)

(x + 2) ^ 2 = 81

x + 2 = √81

x + 2 = 9

x = 9 - 2

x = 7

8)

2x ^ 3 + 1 = 17

2x ^ 4 = 17

2x = 4√17

2x = 2.

031

x = 2.

031 / 2

x = 1.

0155

9)

7x ^ 2 - 3 = 60

7x ^ 1 = 60

7x = 60

x = 60 / 7

x = 8, 57.
