Answer:

Mom=30 Daughter=6

Step-by-step explanation:

M=5×D

M+6=3×D

5D=3D-6

2D=6

D=12

M=12×3=36

Now: D=12-6=6

M=36-6=30

x = daughter's age

so:

5x = 6 + 3x

5x - 3x = 6

2x = 6

x = 6/2

x = 3

now just do the equations to find her age

mother before 6 years: 5 x 3

mother after 6 years: 3 x (3+6)

Hopefully, this helps! If it doesn't tell me in the comments so I can explain it better!
