#1**+1 **

Hey there!

Here I'm going to assume that the angles and lengths represented by the unknowns are equivalent. Thus we can let them equal eachother and solve for the unknowns. For \(x\)

\(3x+3=6x-18\)

\(3x=21\)

\(\therefore x=7\)

For \(y\):

\(7y-3=2x+4\) we know what \(x\) is so we can sub that in and solve for \(y\)

\(7y=21\)

\(\therefore y=3\)

Hope this helped :)
