Answer:
40 gold notebooks
Step-by-step explanation:
5:3 gold notebooks to red notebooks so using this we can set up a proportion
5 x
-- = ---
3 24
cross multiplying
3x = 120
x= 40
so there are 40 gold notebooks if there are 24 red notebooks
Answer:
No
Step-by-step explanation:
We can't use 2x + c = d for solving 2x + 1 = 9 . Here we can find the value of x from 2x + 1 = 9.

Putting the value of x in 2x + c = d :-

But still we don't know the exact value of c & d . If in the question at least we could have got one exact value of either c or d , then we could find out the value of other variable.
The equation will be
8 / 2 = 4
In the repeated subtraction since in actuality division is the larger numbers which is just subtraction.
it becomes,
8 - 2 -2 = 4
8 -2 = 6 - 2 = 4
