X + 3y = 65x - 2y = 13

1.

X + 3y = 6x = 6 - 3y2.

5x - 2y = 135x = 13 + 2yx = 13 + 2y / 5

x = x6 - 3y = 13 + 2y / 55(6 - 3y) = 13 + 2y30 - 15y = 13 + 2y30 - 13 = 2y + 15y17 = 17y17 / 17 = y1 = yx = 6 - 3yx = 6 - 3(1)x = 3(1, 3)

x + 6y = 27(2)7x - 3y = 9

x + 6y = 2714x - 6y = 1815x = 45

x = 45 / 15x = 3 x + 6y = 273 + 6y = 276y = 27 + 3y = 30 / 6y = 5.
