2d + 3 = 11
subtract 3 from each side
2d + 3 - 3 = 11 - 3
2d = 8
divide both integers by 2
(2/2)d = 8/2
d = 4
=======check in original equation
2(4) + 3 = 11
8 + 3 = 11
11 = 11
=========checks
= -2d - 3
it equals 28
-3
The answer is 21 because if 21 is divided by 3 it equals 7 plus 4 equals 11.
4x2 plus 3=11
No. It's -11
