Substitute the value of x in equation 2. Then you'll get y=3. Then again substitute the value of y in x=1+y, you'll get x=4

Y=3,x=4
You plug in 1+y for x in the other equation so it becomes 2y+1+y=10
Then, you combine the 2y and y to make 3y so its 3y+1=10
Then, move the 1 over so you get 3y=10-1 which makes 3y=9
Then, divide the 3 and you end up with y=3 

To find x 
plug y back into the ORIGINAL formula x=1+y OR 2y+x=10
assuming u used x=1+y you would get x=1+3
which gives you x=4

Dan had 15 cups<br> Of apple juice he wanted to add 6 oz how much would he have in the end?
yaroslaw [1]
If you want to know the total, it would be 15 cups and 6 oz. One cup is 8 oz, so 6 oz would have to stand next to 15 cups. 
If  you want to know the total amount of ounces, it would be 126 ounces. 
This information is only accurate if you are using USA  measurements. 
Hope this helps! Have a happy holiday!
