 Question 77943: Help I cant figure this out!!! Please break it down fo rme so i can understand it. Thank you 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 solutions.” -7x + y = 4 2x + 8y = 0 Answer by stanbon(57219)   (Show Source): You can put this solution on YOUR website!-7x + y = 4 2x + 8y = 0 ------------- Solve the 1st equation for Y; y=7x+4 Substitute that into the 2nd equation to solve for x: 2x+8(7x+4)=0 2x+56x+32=0 58x = -32 x=-16/29 -------- Substitute that in y=7x+4 to solve for y: 7(-16/29)+4=-112/29 + 116/29 = 4/29 --------- Solution: x=-16/29 ; y=4/29 ============ Cheers, Stan H.
