Question

a) 4x – 8y + 3m + 6x + 18y -13m
b) 7bc – 2b + 6 – 14bc – 13 – 5b
c) 25p – 50q + 15 -40p +35q
d) 8x – 12 + 5x + 3x +9x
e) 9f – 10g + 3 – 9f + 10g – 3

Answer 1

a)

$4x - 8y + 3m + 6x + 18y - 13m \\ 4x + 6x - 8y + 18y + 3m - 13m \\ 10x + 10y - 10m$

b)

$7bc - 2b + 6 - 14bc - 13 - 5b \\ 7bc - 14bc - 2b - 5b + 6 - 13 \\ - 7bc - 7b - 7$

c)

$25p - 50q + 15 - 40p + 35q \\ 25p - 40p - 50q + 35q + 15 \\ - 15p - 15q + 15$

d)

$8x - 12 + 5x + 3x + 9x \\ 8x + 5x + 3x + 9x - 12 \\ 25x - 12$

e)

$9f - 10g + 3 - 9f + 10g - 3 \\ 9f - 9f - 10g + 10g + 3 \\ 0 + 3 \\ 3$

Espero te sirva de ayuda ✨
