\blue{\bold{\underline{\underline{Given :}}}}

Given:

x - y = 1x−y=1

x = 1 + yx=1+y

Putting The Value Of \small\pink{x}x in the Equation

\rm\pink{3 \times ( - 1) + 4y = 10}3×(−1)+4y=10

\rm\pink{4y = 13}4y=13

\rm\pink{y = \frac{13}{4} }y=

4

13

Putting The Value Of \small\pink{y}y in The Equation

\rm\pink{3x + 4 \times \frac{13}{4} = 10}3x+4×

4

13

=10

\rm\pink{x = - 1}x=−1
