Question

Simplifique as expressões: (a) x+2x+4y+2y. (b) 3a-4b+6a (c) 20w+4z+4w-8z. (d) 5x+4y-20x-4y. (e) 4.5y. (f)-20.4x

Answer 1

Resposta:

(a): 3x + 6y. (b): 9a -4b. (c): 24w -4z. (d): -15x. (e): 20y. (f): -80x.

Explicação passo a passo:

Combine os termos semelhantes.

(a): x + 2x + 4y + 2y —> x + 2x = 3x. 4y + 2y = 6y.

(b): 3a - 4b + 6a —> 3a + 6a = 9a.

(c): 20w + 4z + 4w - 8z —> 20w + 4w = 24w. 4z - 8z = -4z.

(d): 5x + 4y - 20x - 4y —> 5x - 20x = -15x. 4y - 4y = 0.

(e): 4 . 5y = 20y.

(f): -20 . 4x = -80x.

O processo que fiz acima chama-se simplificação.
