Como se resuelven estas ecuaciones2x + 7 = 155x - 1 = - 154x - 3 = 21 - 2 = 2x - 84x - 1 = 2x + 95x + 3 - 2x = x - 174(x - 3) = 285(2x + 1) = 4(3x - 1) - 5(x + 1) = 02(3x + 5) = - 3(4x - 6)?

Como se resuelven estas ecuaciones 2x + 7 = 15 5x - 1 = - 15 4x - 3 = 21 - 2 = 2x - 8 4x - 1 = 2x + 9 5x + 3 - 2x = x - 17 4(x - 3) = 28 5(2x + 1) = 4(3x - 1) - 5(x + 1) = 0 2(3x + 5) = - 3(4x - 6).

2x + 7 = 15

2x = 8

x = 4

5x - 1 = - 15

5x = - 14

x = - 14 / 5

4x - 3 = 21

4x = 24

x = 6 - 2 = 2x - 8 - 2 + 8 = 2x

6 = 2x

3 = x

4x - 1 = 2x + 9

2x = 10

x = 5

5x + 3 - 2x = x - 17

4x = - 21

x = - 21 / 4

4(x - 3) = 28

4x - 12 = 28

4x = 40

x = 10

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

10x + 5 = 12x - 4

9 = 2x

9 / 2 = x - 5(x + 1) = 0 - 5x - 5 = 0 - 5x = 5

x = 5 / - 5

x = - 1

2(3x + 5) = - 3(4x - 6)

6x + 10 = - 12x + 18

22x = 8

x = 8 / 22

x = 4 / 11
