Question

necesito 10 ejemplos de ecuaciones lineales faciles

Answer 1

Respuesta:

20 – 7x = 6x – 6. -6x – 7x = -20 -6. – 13 x = -26. x = -26 / -13. x = 2.

- 7x+2 = 10x+5. 7x-10x = 5- 2. -3 x = 3. x = 3/-3. x = -1.

- 6x−5 = 8x+2. 6x−8x = 5+2. -2 x = 7. x = – 7 /2.

- 4x + 4 + 9x + 18 = 12 (x+2) 4x + 4 + 9x + 18 = 12 x+ 24. 4x + 9x – 12 x = -4 -18 + 24. 13 x – 12 x = -22 + 24. x= 2.
