me ayudan por favor
ECUACIONES LINEALES

17x-8x+2x=3x-2

-14x-15x+2=12-17x

8x+4x-8=7x-8

7x+2+7x=8x-12x

9x-3x+7=9x-8x

DOY 50 PUNTO.....

Answer 1

1.
$17x - 8x + 2x = 3x - 2 \\ 11x - 3x = - 2 \\ 8x = - 2 \\ x = \frac{ - 1}{4}$
2.
$- 14x - 15x + 2 = 12 - 17x \\ - 29x = 10 - 17x \\ - 10 = 29x - 17x \\ - 10 = 12x \\ \frac{ - 5}{6} = x$
3.
$8x + 4x - 8 = 7x - 8 \\ 12x - 8 = 7x - 8 \\ 5x = 0 \\ x = 0$
4.
$7x + 2 + 7x = 8x - 12x \\ 14x + 2 = - 4x \\ 18x = - 2 \\ x = \frac{ - 1}{9}$
5.
$9x - 3x + 7 = 9x - 8x \\ 7 = - 5x \\ - \frac{7}{5} = x$
