Question

-3-2x=12-7x
8x-6=6x+12
9x-4=4x+16
8x-3=7x-4
9x+36=7x-42
6(x-24)=1(x+26)

porfavor no le entiendo :<​

Answer 1

3 - 2x = 12 - 7x

3 - 12 = -7x + 2x

-15 = -5x

-3 = x,,

8x - 6 = 6x + 12

8x - 6x = 12 + 6

2x = 18

x = 6,,

9x - 4 = 4x + 16

9x - 4x = 16 + 4

5x = 20

x = 4,,

8x - 3 = 7x - 4

8x - 7x = -4 + 3

x = -1,,

9x + 36 = 7x - 42

9x - 7x = -42 + 36

2x = -6

x = -4,,

6(x - 24) = 1(x + 26)

6x - 144 = 1x + 26

6x - 1x = 26 + 144

5x = 170

x = 34,,

No soy buena para las matemáticas. Pero espero haberte ayudado... ☺.
