Question

2)Resolva as subtrações de monômios:
a)(+8x)-(-3x) =
b) (-5x)-(-11x) =
c) (-6y)-(-y) =
d) (+7y) -(+7y) =
e) (-3x) -(+4x) =
f) (-6x)-(-x) =
g) (+2y) -(+5y) =
h)(-m)-(-m) =​

Answer 1

Resposta:

a) 8x -(-3x) = 8x + 3x = 12x

b) -5x + 11x = 6x

c) -6y + y = -5y

d) 7y - 7y = 0

e) -3x - 4x = -7x

f) -6x + x = -5x

g) 2y - 5y = -3y

h) -m + m = 0
