Answer:
[tex] \huge{ \boxed{ \bold{ \sf{no \: solution}}}}[/tex]
Step-by-step explanation:
Remember that the equal terms on both side should be cancelled.
[tex] \dashrightarrow{ \sf{ \cancel{5x} \: - 7 = \cancel{ 5x }}}[/tex]
[tex] \dashrightarrow{ \sf{ - 7 = 0}}[/tex]
The statement is false for any value of x. It cannot be further solved! So , 5x - 7 = -5x doesn't have any solution.
Hope I helped!
Have a wonderful time ! ツ
