Answer 1

Resposta:

Explicação passo-a-passo:

i) (-8x) - (-8x) = -8x+8x-->0x

i)(-3xy) + (-9xy) = -3xy-3xy-->-12xy

k) (+5a)-(-2a)+(-3a)= +5a+2a-3a-->7a-3a-->+4a

1)(7x) + (-2x) + (+x) = 7x-2x+x-->8x-2x-->+6x

m) (-6xy) - (-3xy) - (-2xy) = -6xy+3xy+2xy-->-6xy+5xy-->-xy ou -1xy

n) 6x +(2x-4) = 6x+2x-4-->8x-4

o) 7y -(5y-3) = 7y-5y+3-->2y+3

p)4x - (-3x +9 -2x) =4x+3x-9+2x-->9x-9
