why not do it the hard way and waste precious time? a+b =11, a-b =8 a= 11-b , 8+b 11-b =8+b 2b=3 b=1.5, so a = 9.5 9.5^2 =90.25 -1.5^2 = 2.25 =88 Log in to Reply

why not do it the hard way and waste precious time?
a+b =11, a-b =8
a= 11-b , 8+b
11-b =8+b
2b=3
b=1.5, so a = 9.5
9.5^2 =90.25
-1.5^2 = 2.25
=88
