ayudaa

E) 5. (7-x)=31-x

F) 4.(2-3x)= -2x -27​

G) 6x -8 = 4 . (-2x +6)

H) 3. (2x + -2) = 2 . (3x +9)

I) 3. (4x +7) = 4x -25

J) 7x +15 = 3 . (3x -7)

Answer 1

E) 35 -5X = 31 -X
-5X +X = 31 -35
-4X = -4
X = -4/-4
X = 1

F) 8 -12X = -2X -27
-12X +2X = -27 +8
-10X = -19
X = -19/-10
X = 19/10

G) 6X -8 = -8X +24
6X +8X = 24 +8
14X = 32
X = 32/14
(simplificado— X = 16/7)

H) 6X -6 = 6X +18
6X -6X = 18 +6
0X = 24
X = 24/0
X = sin solución

I) 12X +21 = 4X -25
12X -4X = -25 -21
8X = -46
X = -46/8
(simplificado— X = -23/4)

J) 7X +15 = 9X -21
7X -9X = -21 -15
-2X = -36
X = -36/-2
X = 18
