There is no need to simplify this, it is only a sum.
21 + (10/2) - 18 = 8
86
n - 10 + 9n - 3 n + 9n - 10 - 3 10n - 13
20
10^2 minus 4 times 8 divided by 8 plus 9 is equal to 105.
10
17
The result of the expression 5 multiplied by 3, divided by 2, plus 4, minus 1 is 10.
the answer is y minus 10 divided by 2.
30/0.5 = 60 + 10 - 2 = 68
50/10+16-19= 2
If you mean 'simplify': (3x + 5)/15 I simply divided the coefficients (numbers) by 2.
4.1 for sure
