19 + 4h = 1 - 5h

H =

!

19 + 4h = 1 - 5h

You need to get like terms together first by adding 5h to both sides

19 + 4h + 5h = 1 - 5h + 5h

19 + 9h = 1

Next subtract 19 from both sides

19 - 19 + 9h = 1 - 19

9h = - 18

last step is to divide both sides by 9

9h/9 = - 18/9

h = - 2 is the answer

Subtract 4h on both sides - - 19 = 1 - 9h

then subtract 1 on both sides - - 18 = - 9h

divide and h = - 2
