Question

Simplifique as expressões algébricas.
a) 7a + 4a
b) 9y – 4y + y
c) 5(x – 2) + 6(x + 3)
d) 2w – 2 + 3(w – 1)
e) 2T + 3( T – 4) + 12T + 3( -T + 4)
f) 4P – 3(P + 2) – 6 + 5P
g) L – 5(L + 10) + 4( -L + 3)

Answer 1

Resposta:

a) 11a

b) 6y

c) 5x - 5 + 6x + 18 = 11x = 13 ; x = 13/11

d)2w -2 + 3w - 3 = 5w = 5; w = 1

e)2T + 3T - 12 + 12T + (-3T) + 12 = 14T

f)4P - 3P +(-6) - 6 + 5P = 6P -12

g) L - 5L - 10 + (-4L) + 3 = -8L - 7
