Question

resuelve:10|x-2|²+13|x-2|=3​

Answer 1

Respuesta:

A) 6(7-x) = 8(6-x)

42-6x = 48 - 8x

8x-6x = 48 - 42

2x = 6

X= 6/2

X=3

B) - 8(10-x) = - 6

-80 +8 x = -6

8x = 80-6

X = 74/8 simplificando

X= 37/4

c) (x+2).3=(13-x).4+3

3x+6 = 52 - 4x +3

3x +4x = 55-6

7x= 49

X= 49/7

X = 7

d)3(1-2x)+12=10-2(x-3)

3-6x +12 = 10 - 2x +6

15 - 6x = 16-2x

15-16 = 6x-2x

-1 = 4x

X= - 1/4
