Answer 2

Answer:

$A = 20$ and $B = -60$

Step-by-step explanation:

A system with infinite number of solutions is formed by equations which are a multiple of the other one. Then, the following proportion must be observed:

$\alpha = \frac{10}{-10} = \frac{-A}{20} = \frac{60}{B}$

$\alpha = -1$

$-\frac{A}{20} = -1$

$A = 20$

$\frac{60}{B} = - 1$

$B = -60$

The values are $A = 20$ and $B = -60$.
