Question

8y+{4y-[6x-y-(4x-3y)-y]-2x}=

Answer 1

8y+{4y-[6x-y-(4x-3y)-y]-2x }
8y+{4y-[6x-y-4x+3y-y]-2x}
8y+{4y-[2x+y]-2x}
8y+{4y-2x-y-2x}
8y+3y-4x
11x-4x
Obs.:O sinal de menos, troca o sinal de todos

Answer 2

8y + {4y - [ 6x - y - 4x+3 - y ] - 2x] - 4x
8y+{4y-6x+y+4x-3y+y}
8y+4y-6x+y+4x-3y+y
11y+(-2x)
11y-2x
