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: 2x10=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
M10=3(D10)
the second one becomes
M=3(D10)+10
set this equation equal to the first, and solve for D.
