N + d = 21
0.5n + 0.10d = 1.35
5n + 10d = 135
d = 21-n
5n + 210 - 10n = 135
-5n = -75
n = 15
d = 6

2x-3>11-5x
Simplify both sides of the equation
2x-3>-5x+11
Add 5x to both sides
2x-3+5x>-5x+11+5x
7x-3>11
Add 3 to both sides
7x-3+3>11+3
7x>14
Divide both sides by 7
7x/7>14/7
x>2
I hope that's help !
