Answer 10

\[2x + 2y = 17 \]
\[4x - y = 25\]

I already see a variable somewhat isolated, so lets start with finding what y is equal to in the second equation.

\[4x - y = 25\]
\[4x = 25 + y\]
\[4x - 25 = y\]

Now that we know what y is equal to, we can input this value into the second equation

\[2x + 2y = 17 \]
\[2x + 2(4x - 25) = 17\]
\[2x + 8x - 50 = 17\]
Like terms

\[10x - 50 = 17\]
\[10x = 67\]
\[x = \frac{ 67 }{ 10 }\]
\[x = 6.7\]
