1/2(x+6)=2x and 5 - 2x = 7x -h what is the value of h

First solve for x then h

first equation

1/2(x+6)=2x
times both sides by 2/1
x+6=4x
minux both sides
6=3x
divide by 3 both sides
2=x

sub into other equation

5-2x=7x-h
5-2(2)=7(2)-h
5-4=14-h
1=14-h
minus 14 both sides
-13=-h
times -1
13=h
h=13

The answer is a because i went through all the other ones that it didn’t come out right
