Question

Efectua las siguientes operaciones a)2x+3x+1
b)2+3b-a-2b
c)3a-2b+a-3b+5a
d)5x-2xy+4x-y+3xy

Answer 1

Resolver.

2 + 3b - a - 2b =
2 + (3b - 2b) + a =
2 + (b) + a =
2 + b - a
--------------------------------
3a - 2b + a - 3b + 5a
(3a + 5b) + (- 2b - 3b) + a =
8a +( -5b) + a =
8a - 5b + a
------------------------------------------
5x - 2xy + 4x - y + 3xy =
(5x + 4x) + ( -2xy + 3xy) -y =
9x + (xy) - y =
9x + xy -y

Answer 2

b=5b+3a        a=5x+1

c=9a+5b
d=9x+5xy
