The value of Y would be -5 = 2y
Answer:
Total crackers on the plate are 12
Step-by-step explanation:
Manuel ate crackers = ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
His brother ate crackers = ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Crackers left on the plate = 5
We need to find how many crackers were there on the plate.
Let x be the total crackers on the plate
So, we can write the equation
![x-\frac{1}{3}x-\frac{1}{4}x=5](https://tex.z-dn.net/?f=x-%5Cfrac%7B1%7D%7B3%7Dx-%5Cfrac%7B1%7D%7B4%7Dx%3D5)
Because 1/3 and 1/4 crackers are eaten and 5 are left so, we subtract 1/3x and 1/4x from x and equal it to 5
![\frac{12x-4x-3x}{12}=5\\\frac{12x-7x}{12}=5\\\frac{5x}{12}=5\\x=\frac{5*12}{5}\\x=12](https://tex.z-dn.net/?f=%5Cfrac%7B12x-4x-3x%7D%7B12%7D%3D5%5C%5C%5Cfrac%7B12x-7x%7D%7B12%7D%3D5%5C%5C%5Cfrac%7B5x%7D%7B12%7D%3D5%5C%5Cx%3D%5Cfrac%7B5%2A12%7D%7B5%7D%5C%5Cx%3D12)
So, we get x = 12
Therefore, total crackers on the plate are 12
When you solve proportions, you have to cross multiply.
9 x
--- = --- Multiply each numerator by the opposite denominator.
11 22
(9)(22) = 11x Then, multiply.
198 = 11x Then, divide.
18 = x
