Question

Resultado de x-2(x+3)=-[4+(10-x)-3x]+5​

Answer 1

Respuesta:

x - 2(x + 3) = -[4 + (10 - x) - 3x] + 5

x - 2x - 6 = -[4 + 10 - x - 3x] + 5

-x - 6 =  -[14 - 4x] + 5

-x - 6 = -14 + 4x + 5

-x - 4x = -14 + 5 + 6

-5x = -3

x = -3/-5

x = 3/5

Comprobación ​

x - 2(x + 3) = -[4 + (10 - x) - 3x] + 5

3/5 - 2(3/5 + 3) = -[4 + (10 - 3/5) - 3(3/5)] + 5

3/5 - 2(18/5) = -[4 + 47/5 - 9/5] + 5

3/5 - 36/5 = -[58/5] + 5

-33/5 = -58/5 + 5

-33/5 = -33/5
