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!
