Answer:
h = -8/5
Step-by-step explanation:
21 = -4h +13-h
simplify the right side
21 = -5h + 13
subtract 13
21 = -5h + 13
-13 - 13
8 = -5h
divide by -5
8 = -5h
/-5 /-5

K + a + h = 50
a = 2h
k = h - 10
(h - 10) + 2h + h = 50
4h - 10 = 50
4h = 50 + 10
4h = 60
h = 60/4
h = 15 <=== Henry sent 15
a = 2h
a = 2(15)
a = 30 <=== Aldo sent 30
k = h - 10
k = 15 - 10
k = 5 <=== Keiko sent 5
