Question

POR FAVOR AYÚDENME, NECESITO AYUDA
-15x = -45
6x + 9 = 15x -3
-2x + 1 = 6x + 4
x - 15 = 3
2 + x = -5

Answer 1

-15x = -45
x = -45/-15
x = 3

6x + 9 = 15x - 3
9 + 3 = 15x - 6x
12 = 9x
12/9 = x
1,3 = x

-2x - 6x = 4 - 1
-8x = 3
x = 3/-8
x = -0,375

x - 15 = 3
x = 3 + 15
x = 18

2 + x = -5
x = -5 - 2
x = -7

Espero haberte ayudado!
