replace x with A and y with 6 to get:

5A + 2*6 = -12

simplify to get:

5A + 12 = -12

subtract 12 from both sides of the equation to get:

5A = -24

divide both sides of the equation by 5 to get:

A = -24/5

your original equation is 5x + 2y = -12

replace x with -24/5 and y with 6 to get:

5 * -24/5 + 2 * 6 = -12

simplify to get:

-24 + 12 = -12

subtract 12 from both sides to get:

-12 = -24

this confirms that A = -24/5 is a solution to the equation.
