a) 2a+(3a-2b)=2a+3a-2b=5a-2b
b)-4x+(-2x+4y+1)=-4x-2x+4y+1=-6x+4y+1
c)-bx+(8x-2y+x)= -bx+8x-2y+x=-bx+9x-2y=x(-b+9)-2y
d)(-2x+3y)+(5x-5y+1)=-2x+3y+5x-5y+1=3x-2y+1
a) 2a+(3a-2b)=2a+3a-2b=5a-2b
b) -4x+(-2x+4y+1)=-4x-2x+4y+1=-6x+4y+1
c) -bx+(8x-2y+x)=-bx+8x-2y+x=-bx-2y+9x
d) (-2x+3y)+(5x-5y+1)=-2x+3y+5x-5y+1=-2y+3x+1
Proszę:)
