Dane są sumy algebraiczne : S=8x-4y - 1; R= -5y-3x+2 ; W= x-2y
a] S-R b] 2W-S c] -0,5S-4W d] R*W+3S
Błagam o pomoc !!
a)S-R = y + 11x - 2
b)2W-S= 2x-4y - 8x+4y= -6x
c) -4x+2y+0,5 - 4x + 8y = -8x + 10y + 0,5
d) -5yx +10y^2 -3x^2 + 6xy + 2x - 4y + 24x - 12y = -5yx +10y^2 -3x^2 + 6xy + 26 x - 12y
damn
