x+y=30 x-y=6 resolver con método de suma y resta

Rpt≈ x=18, y=12

Resolvemos -

\begin{gathered}x + y = 30 \\ x - y = 6\end{gathered}

x+y=30

x−y=6

\begin{gathered}x + y = 30 \\ x = 6 + y\end{gathered}

x+y=30

x=6+y

6 + y + y = 306+y+y=30

y = 12y=12

x = 6 + 12x=6+12

x = 18x=18

(x, y) =(18, 22)

--------------- verificamos

\begin{gathered}18 + 12 = 30 \\ 18 - 12 = 6\end{gathered}

18+12=30

18−12=6
