I think you should combine like terms
33 photos in a 4x to 7x ratio
4x + 7x = 33
11x = 33
x = 3
33 photos can be put in a 4(3) to 7(3) ratio
which is a 12 to 21 ratio
so 12 photos on one side, and 21 on the other side to get the ratio of 4 to 7
Note:

Answer:
-80
Step-by-step explanation:
We have: -6 = 
+ 4. In order to solve for x, we need to isolate it; in order to isolate x, we have to "undo" order of operations.
The regular order of operations is PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction.
Here, since we're solving for x, we need to go backwards. So, first, subtract 4 from both sides:
-6 - 4 = + 4 - 4 ⇒ -10 =
Then, multiply by 8 on both sides:
-10 * 8 = * 8 ⇒ x = -80
Thus, x = -80.
Hope this helps!
Answer:
There are infinite solutions that solve the system 
Step-by-step explanation:
- The solution can be expressed as (there are infinite solutions that solve the system). This results from rearranging terms in the first or second equation.
- This is because the first equation is a linear combination of the second one (this is, the first equation equals (-1) times the second equation). This means that the second equation does not add any information about x and y: it says exactly the same as the first equation about the relationship between x and y.
- Then, in terms of solving the system, you have one unique expression (not repeated) that shows the relationship between y and x. This means that, any pair of (x,y) that meet the requirements expressed by , will solve the system. Then we have infinite solutions.
