Ayudameeeeeeee.

Answer 1

Respuesta:

1) 2x+7=-30: 2x= -30 -7 , 2x = -37 , x = -37/2 , x = -18.5

2)5x+(-7)=x-(-9) 2 : 5x-7 = x + 9 . 2 , 5x-7 = x+18 , 5x = x+18+7 , 5x = x+25 , 5x - x = 25 , 4x = 25 , x = 25/4 , x = 6.25

3)-9+6x=15+2x 9 : -9+6x=2x+24 , 6x=2x+33 , 4x=33 , x = 4/33 , x = 0.12

4)5x-1=9 -6 : 5x-1=3 , 5x=4 , x = 4/5 , x = 0.8

5)4x-2=8+3x 4 : 4x-2=3x+12 , 4x=3x+14 , 4x - 3x = 14 , x = 14

6)-6+2x-5=5x+10-3 -5 : -6+2x=5x+10-3 , -6+2x=5x+7 , 2x=5x+13 , -3x=13 , x = 13/ -3 = -4.3

7)8+12x=15x-19 6 : 12x=15x-204 , -3x=-204 , x= -204/3 , x=68
