Step-by-step explanation:

\left \{ {{x + 5y = 0} (1) \atop {3y + 2x = -21}(2)} \right.  \left \{ {{x = -5y} \atop {3y + 2x = -21}} \right.    \left \{ {{x = -5y} \atop {3y + 2*(-5y) = -21}} \right.  \left \{ {{x = -5y} \atop {3y - 10y = -21}} \right. \\ \left \{ {{x = -5y } \atop {-7y = -21}} \right.  \left \{ {{x = -5y} \atop {y= 3 }} \right.  \left \{ {{x = -5 * 3} \atop {y=3}} \right.=> \left \{ {{x=-15} \atop {y=3}} \right.

Use the distance formula to find the distance between coordinates.

d = \sqrt{(2--4)^2 + (5-0)^2} \\d = \sqrt{(2+4)^2 + (5)^2} \\d = \sqrt{(6)^2 + (5)^2} \\d = \sqrt{36 + 25} \\d = \sqrt{61} \\d=7.81
