Question

2) Resolver las siguientes ecuaciones aplicando previamente la propiedad distributiva.
a)5. (x + 1) = 2x + 17 = 217
(.1+1 ) 2 1+17= 17
b)7x − 5 = 3. (x + 9) = 9
7 1-5 = 3. (1 + 9) = 19
c) 2. (3x − 8) = 3x + 5 = 35
2 1(3 1-8) = 3 1 + 5 = 315
d)4(x − 3) = 2x + 4 = 24
4(1 - 3 ) = 2 1 + 4 = 214

Answer 1

$\\\\b ) 7x - 5 = 3x + 27 = 9 * 71 - 5 = 3 + 27= 19\\7x - 3x = 19 + 5 - 27 - 639 + 5 - 3 - 27\\4x = - 667\\x = - 667 / 4\\x = - 166.75\\c ) 6x - 16 = 3x + 5 = 22785 - 5880 = 31 + 5 = 315\\6x - 3x = 315 + 16 - 5 - 22785 + 5880 - 31 - 5\\3x = - 16615\\x = - 5538.33333\\\\d ) 4x - 12 = 2x + 4 = 96 - 288 = 21 + 4 = 214\\4x - 2x = 214 + 12 - 4 - 96 + 288 - 21 - 4\\2x = 389\\x = 389 / 2\\x = 194.5$Respuesta:

$5x + 5 = 2x + 17 = 217 + 21 + 1 + 17 = 17\\5x - 2x = 17 - 17 - 217 - 21 - 1 - 17\\3x = - 256\\x = - 256 / 3\\x = - 85.33333$
