3{4(2-7)-11-2[3(-5-1)]} = 3{4 (-5)-11-2[3 (-6)]} ​

Answer 1

Respuesta:

15=15

Explicación paso a paso:

3{4(2-7)-11-2[3(-5-1)]} = 3{4 (-5)-11-2[3 (-6)]} =

3{4(-5)-11-2[3(-6)]} = 3{ -20 -11 -2 [ -18]

3{ -20 -11 -2 [ -18]} = 3 { -20 -11 +36}

3{ -20-11+36} = 3 { -31 +36}

3 { -31 +36} = 3(5)

3(5) = 15

15= 15
