Step-by-step explanation:
Two angles; A & B
One fifth of the sum of two angles is 24 degree"
.2(A + B) = 24
Multiply by 5:
A + B = 5(24)
A + B = 120
half of their difference is 14 degree."
.5(A - B) = 14
Multiply by 2
A - B = 2(14)
A - b = 28
Add the two equations
A + B = 120
A - B = 28
--------------Addition eliminates B, find A
2A = 148
A = 148/2
A = 74 degrees
Find B
74 + B = 120
B = 120 - 74
B = 46 degrees
Check solution in the statement:
half of their difference is 14 degree.
.5(74 - 46) =
.5(28) = 14
