Question

Determine if you have to add or subtract. Then find out y's value and then x's value.

2x+3y=23
-2x+y=13​

Answer 1

Answer:

Add

$x=-2$

$y=9$

Step-by-step explanation:

To find the value of $y$, we can add the two equations:

$2x+3y+(-2x+y)=23+13$

$2x+3y-2x+y=36$

$4y=36$

$y=9$

To find for $x$, we can use substitution:

$2x+3y=23$

$2x+3(9)=23$

$2x=-4$

$x=-2$

∴ $x=-2,y=9$

Hope this helps :)
