5x + 8 = - 24 - 2x = 810 = 2x + 6 - 16 = 2 - 9x?
5x + 8 = - 2 4 - 2x = 8 10 = 2x + 6 - 16 = 2 - 9x.
5x + 8 = - 2 4 - 2x = 8 10 = 2x + 6 - 16 = 2 - 9x.
En resumen
Son ecuaciones lineales de una variable, se pueden resolver : 5x + 8 = - 2 5x = - 2 - 8 5x = - 10 x = - 2 4 - 2x = 8 2x = 4 - 8 = - 4 x = - 2 10 = 2x + 6 10 - 6 = 2x 2x = 4 x = 2 - 16 = 2 - 9x 9x = 16 + 2 9x = 18 x = 2.
Son ecuaciones lineales de una variable, se pueden resolver :
5x + 8 = - 2
5x = - 2 - 8
5x = - 10
x = - 2
4 - 2x = 8
2x = 4 - 8 = - 4
x = - 2
10 = 2x + 6
10 - 6 = 2x
2x = 4
x = 2 - 16 = 2 - 9x
9x = 16 + 2
9x = 18
x = 2.
1) 4 - 2x = 8 4 - 8 = 2x - 4 / 2 = x x = - 2
2) 10 = 2x + 6 10 - 6 = 2x 4 = 2x x = 4 / 2 x = 2
3) - 16 = 2 - 9x 9x = 2 + 16 9x = 18 x = 18 / 9 x = 2.
