 Question 161716: Solve the system of equations using the substitution method. If the answer is a unique solution, present it as an ordered pair: (x,y). If not, specify whether the answer is "no solution" or "infinitely many solution." 7x+y=1 3x+2y=-9 Answer by nabla(475)   (Show Source): You can put this solution on YOUR website!from the first: y=1-7x Put that y into the second equation: 3x+2(1-7x)=-9 3x+2-14x=-9 -11x=-11 x=1 If x=1, y=1-7(1)=-6 check: 7-6=1 3-12=-9 yes.
