Question

$12x - 2y = 56 \\ 2x + 15y = 26$
this question solve deletion metod​

Answer 1

Answer:

$12x - 2y = 56\\2x +15y = 26$

$Let, (2x - 15y = 26)$ × $6$

We get,

$12x - 90y = 156$

Now, solving by deletion method,

$+12x - 2y = 56\\+12x +90y = 156$

(-)___(-)____(-)___

$0 -92y = -100$

$=> 92y = 100$

=> y = 100/92

=> y = 25/23

So, x = $\frac{56 + 2(y)}{12}$

=> x = $\frac{113}{46}$

Hence, $x = \frac{113}{46} and, y = \frac{25}{23}$

Hope it helps.
