Answer:7.  x = 58. x = 2, y = 69. x = 21, y = 39Step-by-step explanation:For a parallelogram, the lengths across intersection are equal.7. For a parallelogram, the lengths across intersection are equal.So that,3x = 4x - 54x - 3x = 5  x = 58. For a parallelogram, the lengths across intersection are equal.So that,2x = 4x = [tex]\frac{4}{2}[/tex]x = 2and y - 1 = 2y -77 - 1 = 2y - yy = 6x = 2, y = 69. For a parallelogram, opposite angles have equal value.Thus,3x = (4x - 21)3x = 4x - 21x = 21and 3y = (y + 78)3y = y + 783y - y = 782y = 78y = [tex]\frac{78}{2}[/tex]   = 39y = 39x = 21, y = 39
