Question 891178
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.
