Resolver la siguientes ecuaciones 19 − 3x + 5x = 15 − 4x este es otro 20x + 7 − 2 = 15x + 3.
Resolver la siguientes ecuaciones 19 − 3x + 5x = 15 − 4x este es otro 20x + 7 − 2 = 15x + 3.
ax² + bx + c = 0
En resumen
19 - 3x + 5x + 4x - 15 = 0 6x = - 19 + 15 6x = 4 x = - 4 / 6 x = - 0. 6 20x + 7 - 2 = 15x + 3 20x + 7 - 2 - 15x - 3 = 0 5x + 2 = 0 5x = - 2 x = - 2 / 5 x = - 2. 5.
19 - 3x + 5x + 4x - 15 = 0
6x = - 19 + 15
6x = 4
x = - 4 / 6
x = - 0.
