Answer:
9
Step-by-step explanation:
We can set up a systems of equations to find the value of the third side.
Let's assume that 
is the length of both sides 1 and 2. Let's also assume that 
is the length of the third side.
We know that 
, and looking at the first clue we can make the equation 
.
We can substitute y into the equation .
So the length of the side that is the same as the second is 7.
Now we can plug this into the equation to find .
Hope this helped!
Answer:
65
Step-by-step explanation:
Let x be the number and y be the another one.
x=4y-3
x-y=48
Substitute x=4y-3 into x-y=48
(4y-3)-y=48
3y=51
y=17
[Since we know x is larger than y (4y-3), we need to use y to calculate out x.]
Substitute y=17 into x=4y-3
x=68-3
x=65
