Answer:
a = 5.5
Step-by-step explanation:
6(a - 6) = 2(4 - a)
(6*a) - (6*6) = (2*4) - (2*a)
6a - 36 = 8 - 2a
6a + 2a = 8 + 36
8a = 44
a = 44/8 = 5.5
The midpoint of the segment should be (3, -4)
Answer:
<h2>(5, -10)</h2>
Step-by-step explanation:

6a-11=13
add 11 to both sides cross out -11 with +11
13+11 =24
6a=24
divide 6 on both sides
a= 4
