Answer is the last choice
2a-4/1= -a-1/a-4
Cross multiply
(2a-4)(a-4)= -(a-1)
2a^2-8a-4a+16= -a+1
Bring right to left sign change signs
2a^2-8a-4a+16+a-1=0
Combine like terms
2a^2-11a+15=0
a= 2 b= -11 c= 15
Use quadratic formula
-b+-sq rt of b^2-4ac. Divided by 2a
-(-11) +- 11^2-4(2)(15) divided by 2(2)
11+-sq rt 121-120 divided by 4
11+1 /4. 11-1/4
12/4. 10/4
3. , 5/2

Answer:
h = 1 2/3
Step-by-step explanation:
1/2 (5-2h) = h/2
Multiply each side by 2
(5-2h) = h
Add 2h to each side
(5-2h +2h) = h+2h
5 = 3h
Divide by 3
5/3 = 3h/3
5/3 =h
1 2/3 = h
Check
1/2 (5-2*5/3) = 5/3/2
1/2 ( 5 - 10/3) = 5/6
1/2 ( 15/3 - 10/3) = 5/6
1/2 ( 5/3) = 5/6
5/6 = 5/6
Add all those numbers and divide by 6 will get you 78
