Question

Simplifique as expressões a termos semelhantes:

Letra A- 2x+3x-6x=

Letra B- 3x+2-3+2x+5.(x+1)=

Letra C- 2c+2x-6+2x-8c+4-4x=

Answer 1

Letra A= -1x Letra B= 5x 6

Answer 2

A)
= 2x + 3x - 6x
= 5x - 6x
= - x

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
B)
= 3x + 2 - 3 + 2x + 5.(x + 1)
= 3x - 1 + 2x + 5x + 5
= 5x + 5x - 1 + 5
= 10x + 4

C)
= 2c + 2x - 6 + 2x - 8c + 4 - 4x
= 2c - 8c + 2x + 2x - 4x + 4 - 6
= - 6c + 4x - 4x - 2
= - 6c - 2
