Answer 2

To evaluate the expression (ax + 2ay + bx - 2by) / (ax + bx + ay + by) at x = 1.3 and y = -0.3, we substitute the given values into the expression:

Substituting x = 1.3 and y = -0.3, we get:

(1.3a + 2(-0.3)a + 1.3b - 2(-0.3)b) / (1.3a + 1.3b + (-0.3)a + (-0.3)b)

Simplifying further:

(1.3a - 0.6a + 1.3b + 0.6b) / (1.3a + 1.3b - 0.3a - 0.3b)

(0.7a + 1.9b) / (1a + 1b)

Now we substitute the values of x and y into the expression:

(0.7(1.3) + 1.9(-0.3)) / (1(1.3) + 1(-0.3))

(0.91 - 0.57) / (1.3 - 0.3)

0.34 / 1

The value of the expression at x = 1.3 and y = -0.3 is 0.34.
