Question

250 + 200h = 300 + 180h 250 + 200h = 300 + 180h − 180h − 180h 250 + 20h = 300 h = credit hours

Answer 1

h = 2.5

Explanation:

250 + 200h = 300 + 180h

• subtract 180 from both sides

250 + 200h - 180 = 300 + 180h - 180

250 + 20h = 300

• subtract 205 from both sides

250 - 250 + 20h = 300 - 250

20h = 50

• divide both sides by 20

20h ÷ 20 = 50 ÷ 20

h = 2.5
