Let x be the number of notebooks bought for $10. Let y = number of notebooks for $8
Then x + y = 6 and 10x + 8 y = 56
Now solve (:
Then x + y = 6 and 10x + 8 y = 56
Now solve (:

If you only bought 6 notebooks, how do you get 7 and 5? You need to read the problems carefully.
x = 6-y
10x + 8y = 56
Substitute 6-y for x and solve.
x = 6-y
10x + 8y = 56
Substitute 6-y for x and solve.
