can anyone help me?

OpenStudy (anonymous):

Do you agree that 2AY=AN and 3AY=AC?

OpenStudy (anonymous):

Also, do you agree that 2AX=AM and that 3AX=AB? If so, 2XY=MN and 3XY=BC

OpenStudy (anonymous):

with the knowledge that XY=9, MN=2XY and BC=3XY, can you substitute XY=9 into the equation?

OpenStudy (anonymous):

MN=2(9) and BC=3(9) Solve.

OpenStudy (anonymous):

Do you get it?

OpenStudy (anonymous):

yup :D
