Respuesta:

1) x = 3

2) x = -2

3) t = 1

4) x = -2

5) x = 3

6) z = -2

7) x = 4

8) x = 3

Explicación paso a paso:

1) 5x - 12 = 3

5x = 3 + 12

5x = 15

x = 3

2) 3x + 1 = x - 3

3x - x = - 3 - 1

2x = - 4

x = - 2

3) 5t + 5 = 3t + 7

5t - 3t = 7 - 5

2t = 2

t = 1

4) 3(2x+1) = - 9

6x + 3 = - 9

6x = - 9 - 3

6x = - 12

x = -2

5) 2(2x - 5) = 3(x-1) - 4

4x - 10 = 3x - 3 - 4

4x - 3x = 10 - 7

x = 3

6) 3(z - 2) + 10 = 2(2z + 2) + 2

3z - 6 + 10 = 4z + 4 + 2

4 - 6 = 4z - 3z

-2 = z

7) 2x + 1 = x - 1

3

2x + 1 = 3(x - 1)

2x + 1 = 3x - 3

1 + 3 = 3x - 2x

4 = x

8) 4x - 2 = 2x + 3 - 1

3 3

4x - 6 = 2x + 3 - 3

2x = 6

x = 3
