Question 135416


WELL, YOU ARE RIGHT ON, SO FAR!!!!!!!!!!!!!!!!!GOOD WORK! IT'S A START.

Lets look at this:
----------Four times Nora's age is six less than the grandmother's age--

4x=4 times Nora's age
y-6= six less that grandmother's age, so:

4x=y-6-------------------------------------eq2

In your equation, if we subtract x from each side we end up with:


y=71-x  now lets substitute this into eq2

4x=71-x-6  add x to each side

4x+x=71-x+x-6  collect like terms

5x=65  divide each side by 5

x=13-----------------------------Nora's age

substituting this into your equation, we get:

13+y=71  subtract 13 from each side
y=71-13=58--------------------------------grandmother's age

CK
58+13=71
71=71
and
4*13=58-6
52=52


Hope this helps---ptaylor
