Answer 2

Thanks for your question...

Your required answer :

Given :

• 312x + 138y = 173 ------ ( 1 )
• 138x + 312y = 202 ------ ( 2 )

To find :

• Value of x + y

Solution :

• Add 1 and 2 :

• 312x + 138y + 138x + 312y = 173 + 202
• 450x + 450y = 375
• 450 ( x + y ) = 375
• $x + y = \frac{375}{450} \\ \\ = \frac{75}{90} \\ \\ = \frac{15}{18} \\ \\ = \frac{5}{6}$

Therefore value of x + y is ⅚ .
