Answer:
K (-1,-1)
Step-by-step explanation:
You multiply 3x - y = 3.
So then it's:
6x - 2y = 3
-2x + 2y =6
which equals 4x = 9
Answer:
WY = 180
Step-by-step explanation:
the diagonals of an isosceles trapezoid are congruent , so
ZX = WY , that is
8y - 4 = 7y + 19 ( subtract 7y from both sides )
y - 4 = 19 ( add 4 to both sides )
y = 23
Then
WY = 7y + 19 = 7(23) + 19 = 161 + 19 = 180
