If the system has no solution or an infinite number of solutions state this. 3x + 24y = 24 27x - 15y = -15Answer by MathTherapy(1422)   (Show Source): You can put this solution on YOUR website!Please can someone help me with this problem: solve using substitution method. If the system has no solution or an infinite number of solutions state this. 3x + 24y = 24 27x - 15y = -15 3x + 24y = 24 ---- 3(x + 8y) = 3(8) ----- x + 8y = 8 ---- x = 8  8y ---- eq (i) 27x - 15y = - 15 ---- 3(9x - 5y) = 3(- 5) ----- 9x - 5y = - 5 ----- eq (ii) 9(8  8y)  5y = - 5 ------- Substituting 8  8y for x in eq (ii) 72  72y  5y = - 5 - 72y  5y = - 5 - 72  77y = - 77 y = , or x = 8  8(1) ----- Substituting 1 for y in eq (i) x = 8  8, or Solution: (,) Send comments and thank-yous to D at MathMadEzy@aol.com
