Answer 1

Respuesta:

Explicación paso a paso:

5(x + 1) = 8(x-3)

5x + 5 = 8x - 24

24 + 5 = 8x - 5x

29 = 3x

29/3 = x

9(a-3)= -4(a+2)

9a - 27 = -4a - 8

9a + 4a = 27 - 8

13a = 19

a = 19/13

12(b+8)= -16(b+1)

12b + 96= -16b - 16

12b + 16b = -96 - 16

28b = -122

b = -122/28

b = -4

13+2(x+1)=4(x+2)

13 + 2x + 1 = 4x + 8

14 + 2x = 4x + 8

14 - 8 = 4x - 2x

6 = 2x

3 = x
