\huge\underline\frak{\fbox{AnSwEr :-}}

\implies \large\underline\red{\fbox{x = 2}}

\implies \large\underline\red{\fbox{y = 3}}

Step-by-step explanation:

हमारे पास है

\implies 0.2x + 0.3y = 1.3 . . . ( i )

\implies 0.4x + 0.5y = 2.3 . . . ( ii )

समीकरण ( 1 ) से हम प्राप्त करते हैं

\implies x = \LARGE\sf\frac{t+3}{3} + \LARGE\sf\frac{t}{2}

इस मान को समीकरण ( ii ) में रखने पर ,

\implies 0.4\LARGE\sf\frac{1.3-0.3y}{0.2} + 0.5y = 2.3

\implies 2.6 - 0.6y + 0.5y = 2.3

\implies - 0.1y = - 0.3

\implies \large\underline\red{\fbox{y = 3}}

इस मान को ( ) में रखने पर

\implies 0.2x + 0.3 x 3 = 1.3

\implies 0.2x = 1.3 - 0.9

\implies 0.2x = 0 . 4

\implies \large\underline\red{\fbox{x = 2}}

\implies \large\underline\purple{\fbox{x = 2}}

\implies \large\underline\purple{\fbox{y = 3}}
