What Is The Solution To This System? , X\T+\T4y\T=\T17 Y\T=\T2212x\T+\T11
What is the solution to this system? x + 4y = 17 y = −x + 11 ANSWER : S = { 9 , 2 } STEP BY STEP EXPLANATION : x + 4y = 17 y = -x + 11 ___________________ x + 4(-x + 11) = 17 x - 4x + 44 = 17 x - 4x = 17 - 44 x - 4x = -27 -3x = -27 x = (-27)/(-3) x = 9 ______________ y = -x + 11 y = -9 + 11 y = 2 Therefore , the solution for linear sistem is S = { 9 , 2 } . OK.
