21 + 15 = 36
n + 15 = 36 Therefore, n = 36 - 15 n = 21
x + 21 = 36Subtract 21 from each side:x = 15
51
3 + 8 + 21 + 22 + 36 = 90 Ans.// What do you mean?
Nope, 36 divided by 21 equals 1 with a remainder of 15.
The answer is: 36
15
That would be 90.
15
3+6+9+12+15+18+21+24+27+30+33+36 = 234
10x+15 = 7x-21 10x-7x = -21-15 3x = -36 x = -12 Which is the solution to the above equation when simplified.
36 - 21 = 1536 - 21 = 1536 - 21 = 1536 - 21 = 15
