let x be the flour
now
or,(21/2)+x=42/3
or,(21+2x)/2=42/3
or, 3(21+2x)=42×2
or, 63+6x=84
or,6x=84-63
or, 6x =21
or, x=21/6
thus she need 21/6 cups of flour
0.06 x 0.5 = 0.03 (I think that is what you're asking)
(3x-5y=60)
4x+5y=-4
3(8)-5(7.2)=60
4(8)+5(-7.2)=-4
7x=56
÷7. ÷7
x=8
3(8)-5y=60
4(8)+5y=-4
32+5y=-4
-32. -32
5y=-36
÷5. ÷5
y=7.2
