Question

me ayudan con esto por favor no lo entiendo​

Answer 1

Respuesta:

a. -2x = 9 -x

-2x +x = 9

-1x = 9

X = 9: +1

X= 9

B. -6x = -24 +2x

-6x -2x = -24

-8x = -24

X= -24 : +8

X= -3

c.3x -10 = 18 -x

3x +x -10= 18

4x -10 = 18

4x = 18 +10

4x = 28

X= 28 : -4

X= -7

d. 7x +8 = 3x -4

7x -3x +8 = -4

4x +8 = -4

4x = -4 -8

4x = -12

X= -12 : -4

X = 3

e. -2 -3x +5 = -5 -8x +x

-3x +8x -x= +2 -5 -5

+5x -x = +2 -10

+4x = -8

X = -8 : -4

X = +2

F. x -2 = -3 -2x -8

x +2x = -3 -8 +2

3x = -11 +2

3x = -9

X = -9 : 3

X= -3

g. -5x +27 = -8

-5x = -8 -27

-5x = -35

X = -35 : -5

X = +7
