Question

I. Hallar la solución de las ecuaciones: a) (5x-6) + x = 2x+10
b) 4(x-2) = - 5(x+12)

Answer 1

Respuesta:

a) x = 4

b) x = - 52/9

Explicación paso a paso:

a) (5x - 6) + x = 2x + 10

5x - 6 + x = 2x + 10

6x - 6 = 2x + 10

6x - 2x = 10 + 6

4x = 16

x = 16/4

x = 4

b) 4(x - 2) = - 5(x + 12)

4(x) - 4(2) = (-5)(x) + (-5)(12)

4x - 8 = - 5x - 60

4x + 5x = - 60 + 8

9x = - 52

x = - 52/9
