4x-12x+9=25
2x -3+5
4x+12+8=0
2x -11x +5=0

Answer 1

Oi...

a)

4x - 12x + 9 = 25

- 8x = 25 - 9

- 8x = 16 ( - 1)

8x = - 16

x = - 16/8

x = - 2

b)

2x - 3 + 5

2x + 2

2(x + 1)

c)

4x + 12 + 8 = 0

4x = - 12 - 8

4x = - 20

x = - 20/4

x = - 5

d)

2x - 11x + 5 = 0

- 9x = - 5 (- 1)

9x = 5

x = 5/9

Espero ter ajudado
