SYSTEM OF EQUATIONS
S+B = 17000
0.1S+0.07B=1280
Multiply the first equation by 0.1 and subtract the second equation
0.03B=420
B=14,000
S=3,000
Lets take (-4) - (-6)
= -4 + 6 (here we changed the sign because in integers when you are subtracting <span>an integer, we put its opposite..thats the rule .)
=. -4 + 6 = 2
so here we got the answer as 2 .....this shows that </span>your answer will be less than the integer you started with ....this is because here in subtraction we will first change the sign and then follow the same rules of addition ...so here if both the numbers have opposite signs then we subtract and put the greater number sign .....
