Question

x-13=4[3x-4(x-2)] y tambien



2x+3(x-3)=6[2x-3(x-5)]

Answer 1

Calcular el valor de "x" en las siguientes ecuaciones dadas:
x - 13 = 4 [3x - 4 (x - 2)] = 
x - 13 = 4 [3x - 4x + 8] = 
x - 13 = 4 [- x + 8] = 
x - 13 = - 4x + 32
x + 4x = 32 + 13
5x = 45
x = 45/5
x = 9

Rpt. El valor de x es 9
-----------------------------------------------
2x + 3 (x - 3) = 6 [2x - 3 (x - 5)] = 
2x + 3x - 9 = 6 [2x - 3x + 15] = 
5x - 9 = 6 [- x + 15] = 
5x - 9 = - 6x + 90 =
5x + 6x = 90 + 9
11x = 99
x = 99/11
x = 9

Rpt. El valor de x es 9

Answer 2

x-13=4[3x-4x+8]
x-13=12x-16x+32
x-12x+16x=32+13
-5x=45
x = 45
     --- = 9
      5
x=9
