Answer 1

Answer:  a = 11.1

Step-by-step explanation:

a(0.3 - y) + 1.1 + 2.4x = 0

Let y = 1.3 → a(0.3 - 1.3) + 1.1 + 2.4x = 0 → -a + 1.1 + 2.4x = 0 → a = 1.1 + 2.4x

(y - 1.2) = -1.2(x - 0.5)

Let y = 1.3 → (1.3 - 1.2) = -1.2(x - 0.5) → 0.1 = -1.2x + 0.6 → -0.5 = -1.2x → $\dfrac{50}{12}=x\ \rightarrow\ \dfrac{25}{6}=x$

a = 1.1 + 2.4x

   $=1.1+2.4\bigg(\dfrac{25}{6}\bigg)$

   = 1.1 + 0.4(25)

   = 1.1 + 10

   = 11.1
