Question

ME AYUDAN CONESTAS ECUACIONES ?

a) 3x + 5 - 2x = x + 3 - X

b) 5x - 3+ 2x = 6x + 3x + 4 - 2x -X-6

c) 2x + 4- X = 2x - x + 8 - X

d) 6x-3-4x - x = 5x + 8 - X-6 - 4x

e) 7x + 2-5x = x + 8-X

f) 5x + 10-x-2x = x + 3 - 2x + x + 1​

Answer 1

Respuesta:

$3x + 5 - 2x = x + 3 - x \\ \\ 3x - 2x - x + x = 3 - 5 \\ \\ x = - 2$

▒▒▒▒▒▒▒▒▒▒▒▒

$5x - 3 + 2x = 6x + 3x + 4 - 2x - x - 6 \\ \\ 5x + 2x - 6x - 3x + 2x + x = 4 - 6 + 3 \\ \\ 10x - 9x = 7 - 6 \\ \\ x = 1$

▒▒▒▒▒▒▒▒▒▒▒

$2x + 4 - x = 2x - x + 8 - x \\ \\ 2x - x - 2x + x + x = 8 - 4 \\ \\ x = 4$

▒▒▒▒▒▒▒▒▒▒▒

$6x - 3 - 4x - x = 5x + 8 - x - 6 - 4x \\ \\ 6x - 4x - x - 5x + x + 4x = 8 - 6 + 3 \\ \\ 11x - 10x = 11 - 6 \\ \\ x = 5$

▒▒▒▒▒▒▒▒▒▒▒▒

$7x + 2 - 5x = x + 8 - x \\ \\ 7x - 5x - x + x = 8 - 2 \\ \\ 8x - 6x = 6 \\ \\ 2x = 6 \\ \\ x = \frac{6}{2} \\ \\ x = 3$

▒▒▒▒▒▒▒▒▒▒▒

$5x + 10 - x - 2x =x + 3 - 2x + 2 + 1 \\ \\ 5x - x - 2x - x + 2x = 3 + 2 + 1 - 10 \\ \\ 7x - 4x = 6 - 10 \\ \\ 3x = - 4 \\ \\ x = \frac{ - 4}{3}$
