Marys monthly salary is $500 less than twice her daughter's salary. Together they earn $3,400 each month. How much is the daughter's salary. ans-1,300

500-500-2x=3,400-500

2x=3,100

2x/2=3,100/2

**MathMate**, Friday, April 15, 2011 at 2:54pmYou're close, here's what you could have done:

daughter's salary = X

Mary's salary = 2X-500

Together, they earn

2X-500 + X = 3400

3x = 3400 +500 = 3900

Can you take it from here?
