3x + 4y = 17.....multiply by 4
-4x - 3y = -18 ...multiply by 3
------------------
12x + 16y = 68 (result of multiplying by 4)
-12x - 9y = - 54 (result of multiplying by 3)
------------------add
7y = 14
y = 14/7
y = 2
3x + 4y = 17
3x + 4(2) = 17
3x + 8 = 17
3x = 17 - 8
3x = 9
x = 9/3
x = 3
ur solution is (3,2)

Answer:
yes im pretty sure correct me if im wrong. Good luck!!!!!
Step-by-step explanation:
For this case we have by definition, that each of the four internal angles of a square measure 90 degrees.
If we draw the diagonals of the square then the angles are divided by two, that is:
Thus, angle 3 measures 45 degrees.
By definition, the sum of the internal angles of a triangle is 180 degrees.
So:
Thus, angle 2 measures 45 degrees.
Answer:
45 degrees
