reduza os termos semelhantes A)-4x+6y+10x-2y-x B) x+7x+10y-3x C)2x-8y-6y-y-9x D) 3\2X+1\4Y-1\3X+2Y

Answer 1

Resposta:

Explicação passo-a-passo:

A)

= - 4x + 6y + 10x - 2y - x

= - 4x + 10x - x + 6y - 2y

= - 4x - x + 10x + 6y - 2y

= - 5x + 10x + 4y

= 5x + 4y

b)

= x + 7x + 10y - 3x

= x + 7x - 3x + 10y

= 8x - 3x + 10y

= 5x + 10y

c)  

= 2x - 8y - 6y - y - 9x

= 2x - 15y - 9x

= 2x - 9x - 15y

= - 7x - 15y

d)

3/2x + 1/4y - 1/3x + 2y

3/2x - 1/3 x  +   1/4  y   +  2y

9x/6 – 2x/6 + 1y/4 + 8y

R.

7x/6+9y/4:
