b)x + 3y - 1/3=5+3*1-1/3=8-1/3=7i2/3(ułamek niewłaściwy !!)
c)4m2(potęga) - 2 (m-n)=4*(-3)2(potęga)-2*(-3-8)=4*9-2*(-11)=36+22=58
d)10x + y=10*3-2=30-2=28
e) [3x + (-5)] + (8y - 3)=[3*3+(-5)]+(8*(-2)-3)=[9-5]+(-16-3)=4-8=(-4)
b) 15/3
2*(-2*-2)-3*-2=2*4+6=14
b x +3y-1/3 dla x=5 i y=1
5+3*1-1/37 i 2/3
c 4m<kw>-2(m-n) dla m=-3 i n=8
4*(-3*-3)-2*(-3-8)=36-22=14
d 10x-y dla x=3 i y=-2
10*3-(-2)=32
e (3x+-5)+(8y-3) dla x=3 i y=-2
3*3-5+(8*-2-3)=-4-19=-23
