-3x-y=149x- =-27Use the method of substitution to solve

Answer:The solution to the system of equations is x=3 y= 23  Step-by-step explanation:solving this system of equation using substitution method   -3x-y=14 …..   equation (1)     -9x =-27   ….. equation (2)  Solving for value of x from equation 2  -9x =-27    so x= -27/-9 = 3so x = 3The second equation is solved for x, so we can substitute the expression 3 in for x in the first equation (1)-3x-y=14-3 (3) - y =14  -9-y= 14-9=14+yy=-23The solution to the system of equations is x=3 y= -23  We can check our work by plugging these numbers back into the original equations. Let's try -3x-y=14      -3x-y=14      -3(3) -(-23)= 14-9+23 = 1414= 14Yes, our solution checks out.
