Question

Joseph has 24 cousins. He knows that he has 6 more female cousins than male cousins. How many female cousins does he have? Solve and show all working out.

Answer 1

Write 2 equations for this
Let x = Number of female cousins, y = male cousins

equation 1: x=y+6
equation 2: x+y=24

Now solve for x using substitution.

Answer 2

What do I need to substitute?

Answer 3

Equation 1 tells you the x=y+6.. Substitute this into equation 2 and you get (y+6)+y=24
Now solve that equation for y then we can substitute y into the first equation and solve for x
