Question

4x-(3x+9)=(x+2)-(2x-1

Answer 1

4x-(3x+9)=(x+2)-(2x-1)

4x-3x-9=x+2-2x+1

4x-3x+2x=2+1-9

3x=-6

x=-6/3=-3

x=-3

Answer 2

Respuesta:

6

Explicación paso a paso:

4x - (3x+9) = (x+2) - (2x-1)

4x - 3x - 9 = x + 2 - 2x + 1

x - 9 = -x + 3

x + x = 9 + 3

2x = 12

x = 6

Comprobamos:

4(6) - (3.6 + 9) = (6 + 2) - (2.6 - 1)

24 - (18 + 9) = 8 - (12 - 1)

24 - (27) = 8 - (11)

24 - 27 = 8 - 11

-3 = -3

comprobado: x = 6
