Question

Ajuuuda por favor !!!!
Determine as diferenças :
a) 22 x-(+14x) =
b) (-48ay) - (-38ay) =
c) ( 2x+3y) - (-y+2x) =
d) (5x-4y) - ( 10x-2y+3) =

Answer 1

a) 22X-(+14X)
 = 22X-14X
 = 8X

b) (-48ay)-(-38ay)
 = -48ay+38ay
 = -10ay

c) (2x+3y)-(-y+2x)
 = 2x+3y+y-2x
 = 4y

d) (5x-4y)-(10x-2y+3)
 = 5x-4y-10x+2Y-3
 = -5X-2Y-3
