Plug in (-1, 3) into both equations

Ax - 2y = 4

A(-1) - 2(3) = 4

-A - 6 = 4 Add 6 on both sides

-A = 10 Divide -1 on both sides

A = -10

5x + By = -1

5(-1) + B(3) = -1

-5 + 3B = -1 Add 5 on both sides

3B = 4 Divide 3 on both side

B = $\frac{4}{3}$

$2\sqrt{3}$

------------------------

Steps:

1st write out equation

$\frac{\sqrt{60}}{\sqrt{5}} \\$

Second write the conjugant and multiply it.

$\frac{\sqrt{60}}{\sqrt{5}} * \frac{\sqrt{5} }{\sqrt{5} }$

After multiplying you should get,

$\frac{10\sqrt{3}}{5}$

now after simplifying you should get

$2\sqrt{3}$
