Answer:
x = 5 ; y =1
Step-by-step explanation:
-3x - 1y = -16 ----------(i)
2x + 1 y= 11 ---------(ii) {add (i) and (ii), +1y and -1y will be eliminated}
-x = -5
divide both side by -1
[tex]\frac{-x}{-1}=\frac{-5}{-1}[/tex]
x = 5
Plug in x = 5 in (i)
-3*5 - 1y = -16
-15 - y = -16
-y = -16 + 15
-y = -1
divide both side by (-1)
[tex]\frac{-y}{-1}=\frac{-1}{-1}\\y = 1[/tex]
