Question

RESUELVE 2-x=x-8=
RESUELVE 3+3x-1=x+2+2x=
Reducir los terminnos de la expresion algebraica dada:
15a2-8ab+6a2-6ab-9+4a2-13ab=

Answer 1

Respuesta:

2 - x = x - 8

2 + 8 = x + x

10 = 2 x

x = 10/2

x = 5

VERIFICAMOS

2 - x = x - 8

2 - 5 = 5 - 8

- 3 = - 3 VERIFICADO

RESUELVE

3+3x-1=x+2+2x

3x - x - 2x = 2 - 3 + 1

0 x = 0

x = 0

VERIFICAMOS

3+3x-1=x+2+2x

3 + 3 . 0 - 1 = 0 + 2 + 2.0

3 - 1 = 2

2 = 2 VERIFICADO

15a2-8ab+6a2-6ab-9+4a2-13ab=

(15a² + 6 a² + 4a²) + (-8ab - 6ab - 13 ab) - 9 =

25 a² - 27 ab - 9
