Question

ajuda nos ai, precisamos isso ate umas 4 hrs
simplifique as expressoes:

a) -8x + 5x - 2x + 10 - 2-
b) +12x -4x - 21 - 30-
c) 2(-5x + 9) +52 +9
d) -8(-2x -6) -2 - 6-
e) $\frac{-4x -2x}{2}$ +18 - 37-
f) $\frac{+16x +2x}{9} \frac{-13 +5}{8}$

Answer 1

a) -8x + 5x - 2x + 10 - 2 = -5x + 8

b) 12x - 4x - 21 - 30 = 8x - 51

c) 2(-5x + 9) + 52 + 9 = -10x + 18 + 61 = -10x + 79

d) -8(-2x -6) -2 - 6 = 16x + 48 - 8 = 16x + 40

e) [(-4x - 2x)/2] + 18 - 37 = (-6x/2) - 19 = -3x - 19

f) ?
