(12) (13) geometry

check ans

12) x = 5 y = 2
13 x = 12 y = 13/3

Problem 12)

You are correct. You solve the system
x+1 = 3y
3x-4 = 5y+1
for x and y to find that x = 5 and y = 2

As a check
x+1 = 3y
5+1 = 3*2
6 = 6 ... true equation
and
3x-4 = 5y+1
3*5-4 = 5*2+1
11 = 11 ... true equation
Both equations are true when (x,y) = (5,2) so the answer is confirmed



Problem 13)

Unfortunately the diagram is cut off so its impossible to say at the moment. Please repost this one. Thank you.
