Question

reduza a termos semelhantes.
a) 5x+(7x-12)-(20+4x)
b) 8x+(-0,5)-(-1,2x)
c) (1/3y+1/2x)-(4/3y-3/2x)

Answer 1

5x + (7x -12) - (20 + 4x)
5x + 7x -12 - 20 + 4x
16x - 32
X - 2
8x + (-0,5) - (-1,2x)
8x - 0,5 + 1,2x
9,2x - 0,5
92X - 5
(1/3y + 1/2x) - (4/3y - 3/2x)
1/3y + 1/2x - 4/3y + 3/2x
(1/3y - 4/3y) + (1/2x - 3/2x)
-3/3Y - 2/2X
-Y - X
