John has 9 times as many toys as Jacob. If John gives 12 toys to Jacob, the two children will have exactly the same amount. How many toys do they have altogether?
+592 Let x = Jacob
John has 9x
9x - 12 = x + 12
8x = 24
x = 3
This means Jacob has 3 toys and John has 3 x 9 = 27 toys.
3 + 27 = 30 toys altogether
