Answer 1

Well, we can set the two equations equal to each other, because m = m.
\[10x+4 = 5x-4\]
Can you solve that for \(x\)? Once you have a value for \(x\) plug it back into either one of those equations to find \(m\).

Answer 2

Are you sure you copied the equations properly?

Answer 3

I think it is supposed to be \[10x-4\] and \[5x+4\]
