a)5-9x=8x-12
b)7+2-x=-9x-1
c)3x+2x=10-5
d)-7x+2-3=6x
ayuda

Answer 1

a) 5-9x=8x-12
    -9x-8x=-12-5
     -17x=-17
       x=-17/-17
       x= 1

b)7+2-x=-9x-1
   -x+9x=-1-7-2
    8x=-10
    x=-10/8
    x= -1,25

c)3x+2x=10-5
   5x=5
   x=5/5
   x= 1

d)-7x+2-3=6x
   -7x-6x=-2+3
    -13x=1
     x=1/-13
     x=-0,07

Espero te sirva :)

Answer 2

5-9x = 8x-12
12+5 = 8x+9x
17 = 17x
17/17 =x
1 = x
________________________

7+2-x = -9x-1
9x-x = -1-7-2
8x = -10
x = -10/8
x = -5/4
__________________________

3x+2x = 10-5
5x = 5
x = 5/5
x = 1
___________________

-7x+2-3 = 6x 
-1 = 6x+7x
-1 = 13x
-1/13 =x
