5h+11=13h-21 -5h +21 -5h +21 32=8h /8 /8 4=h
The answer is 21 because if 21 is divided by 3 it equals 7 plus 4 equals 11.

500(2 * 250), (125 * 4) & (4 * 125).
Zero.
There is no variable, and the equation is not valid.
11x+9=7x+21 11x-7x=4 4x+9=21 21-9=12 4x=12 12 divided by 4= 3 x=3
-4 + 21 = 17
7 + 21 + 2 + 86 + 4 = 120
4 + 17 = 21

sqrt(4) + 21 = 2 + 21 = 23
5h+11=13h-21 -5h +21 -5h +21 32=8h /8 /8 4=h
To find the value of d. SO: if d + 21 = 25, subtract 21 from each side, gives d = 25 - 21, so d = 4

3.5 + 5 + 4 + 8.5 = 21
