2y=-x+93×-6y=-15 whats the solution to the system​

Answer:Step-by-step explanation:2y = -x +93x - 6y = -15The solution is the value of x and y that will make the two equations true in the same time. 3x-6y = -15;  divide both sides by 3x-2y = -5; substitute 2y for -x+9 because the first equation tell us they are equalx-(-x+9) = -5; open parenthesisx+x-9 = -5 ; add 9 to both sides  and combine like terms2x = -5 +9; 2x = 4; divide both sides by 2 x= 2Substitute x for 22y = -x+9 ; 2y = -2 +9 ; 2y = 7; y = 7/2 = 3.5Solution is (2, 3.5)
