Ecuaciones lineales : 3× + 5 = 118y - 3 = 132× + 11 = 235m - 7 = 817 × + 10 = 12× + 208n - 20 = 6n - 107× - 4 = 172(× + 3) - 3 = 3(× + 2) + 1?

1)

8y - 3 = 13 8y = 13 + 3 8y = 16 y = 16÷ 8 y = 2 = = >> Respuesta

2)

2x + 11 = 23 2x = 23 - 11 2x = 12 x = 12÷ 2 x = 6 = = >> Respuesta

3)

5m - 7 = 8 5m = 8 + 7 5m = 15 m = 15÷ 5 m = 3 = = >> Respuesta

4) 17x + 10 = 12x + 20

17x - 12 x = 20 - 10 5x = 10 x = 10 ÷ 5 x = 2 = = >> Respuesta

5)

8n - 20 = 6n - 10

8n - 6n = - 10 + 20 2n = 10 n = 10÷ 2 n = 5 = = >> Respuesta

6)

7x - 4 = 17 7x = 17 + 4 7x = 21 x = 21÷ 7 x = 3 = = >> Respuesta

7)

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

2x + 6 - 3 = 3x + 6 + 1 2x + 3 = 3x + 7 2x - 3x = 7 - 3 - x = 4 x = 4÷ - 1 x = - 4 = = >> Respuesta.
