Question

Please help with problem(will post photo below)

Answer 1

You may notice the second and third are already in a single variable. This lets you solve those and test them in the first to see if they are true.

Answer 2

3x=x+5
2x=0 \[\rightarrow x=0\]
6y=10\[\rightarrow y=\frac{ 5 }{ 3 }\]
\[\rightarrow \left( 0,\frac{ 5 }{ 3 } \right)\]

Answer 3
