Start with the equation:
.10d + 50 = .25d + 20
Next step:
subtract 20 from both sides to get:
.10d + 30 = .25d
Next step:
subtract .10d from both sides to get:
30 = .15d, then divide both sides by .15 to get 200 = d
ANSWER: 200 miles...substitute into original equation shown above to check your work...GOOD LUCK!
.10d + 50 = .25d + 20
Next step:
subtract 20 from both sides to get:
.10d + 30 = .25d
Next step:
subtract .10d from both sides to get:
30 = .15d, then divide both sides by .15 to get 200 = d
