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
