Equations Question

posted by .

A mother is twice as old as her daughter now, but ten years ago, she was 3 times as old as her daughter. Fins their ages at present.

I tried to form an equation: 2x-10=3x, but that didn't work. Could someone help me forma working equation for it, and I can take it from there.

Thank you!
Michelle

M=2D
M-10=3(D-10)

the second one becomes
M=3(D-10)+10
set this equation equal to the first, and solve for D.
