Question
Solve the following simultaneous equations $:x – 2y – 2 ; x + 2y = 10$
✓
Answer
$x-2 y=-2$
$x+2 y=10 $
Adding I and II
$2 x=8$
$\Rightarrow x=4$
Putting the value of $x$ in (I) we get
$4-2 y=-2$
$\Rightarrow-2 y=-6$
$\Rightarrow y=3$
$x+2 y=10 $
Adding I and II
$2 x=8$
$\Rightarrow x=4$
Putting the value of $x$ in (I) we get
$4-2 y=-2$
$\Rightarrow-2 y=-6$
$\Rightarrow y=3$
