One serving of this spinach contains 20 calories and 3 grams of protein.
00:07
So, one serving of, i'm just writing that as sp, this contains 20 calories and 3 grams of protein.
00:22
So 20 calories i'm writing in c, 20 calories plus 3 grams of protein.
00:30
So 3 protein.
00:31
And the next thing is one serving of egg content.
00:35
Contains 150 calories, one serving of egg contains 150 calories, so 150 c plus 13 grams of protein.
00:52
So 13 p it will be.
00:55
Now it is asked to find the number of servings of each which combined contains 160 calories at 22 grams of protein.
01:03
Now let's take x serving of sp and y serving egg is taken to get and this hold together will give 160 calories and 22 protein.
01:31
So if this hold together give 160 calories plus 22 grams of protein and we have to find what is the value of this x and y.
01:43
Now if egg serving of this sp is served then we can write that the calories will be 20x plus in one serving it was 3 protein so it will be 3x protein from sp and plus if y servings of egg is given then we can write that 150 y will be the calorie sorry 150 is 150 y will be the calorie plus 13 y will be the we don't have to write this b over here 13 y will be the sorry we have to write this was this was calories and this was protein this was calorie and we have to write this this was protein so this will be 13 why will be the protein now this whole together will give 160c plus 22p now just to reiterate once again what i was explaining over here we are serving x servings of sp and y servings of egg so we know that or it is already given that in one serving of sp there is 20 calories and 3 protein so if one serving contains 20 calorie then x serving will contain 20 into x calories just similar as that so if one serving contains 3 protein then x servings will give 3 into x proteins let's take an example if this value of x is equal to 2 so let's let's think that 2 servants are given so in 1 serving there are 3p so in 2 serving it will be 2 into 3p that is 6 proteins just like that so that is what i have written over here so from this we can write that 160 is equal to 20 x plus 150 y why because this was the calorie from x servings of sp and this was the calorie from y servings of egg so the total calorie needed is 160 so we can write 160 plus what sorry 160 equal to 20x plus 150 y similarly we can write 22 is equal to 3x plus 13 y why because this is the protein this is the protein and this is the rest...
