    I assume you mean:

    12 - 8(4 - 2x) = 4(10x + 21) + 16

    Expanding we get:

    12 - 32 + 16x = 40x + 84 + 16

    so, 16x - 20 = 40x + 100

    i.e. 24x = -120

    => x = -5

    What is the solution of the equation ?

    12 - 8 (4 - 2x) = 4 (10x + 21) + 16

    24x = -120

    x = -5

    Please post in English; use Google translate perhaps. 

    What are the solutions of these two equations  

    12 - 8 (4 - 2x) = 4 

    (10x - 21) = 16  

    --------------------------- 

    A: 12 - 8 (4 - 2x) = 4 

    12 – 32 + 16x = 4 

    16x = 24, s0 x = 3/2 

     

    B: (10x - 21) = 16 

    10x = 37 

    x = 3.7

    12-8(4-2x)=4|+8(4-2x)

    12=4+8(4-2x)

    12=4+32-16x

    12=36-16x|+16x

    12+16x=36|-12

    16x=24|/16

    x=24/16

    x=3/2

    verdade? No se matematicas? Quantos anos tiene? no escuala?? pero ... [-8*(4-2x) es -32 + 16x] y ahora 12 + - 32 + 16x -12 + 32 = 4 - 12 + 32 ... 16x = 24 ... 16x/16 = 24/16 ===___  [ 12 - 32 + 16x = 4 ... ]
