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.
