Answer 2

Answer:

(i) 2x + 3y = 10

(ii) 3x + 2y =15

Adding equation (I) and (ii)

$\blue{\bold{\underline{\underline{}}}}$

• $\sf 2x + 3y = 10 \bf$

• $\sf 3y + 2y = 15 \bf$

$\begin{gathered} :\implies\sf{ 5x + 5y = 25 } \\ \\ \\:\implies\sf { 5( x + y) = 25 } \\ \\ \\ :\implies\sf{ x + y } = \dfrac{ 25 } { 5} \\ \\ \\ :\implies\sf { x + y = 5 }\end{gathered}$

Hope it helps uh!
