Answer:
You start off with the equation:
[tex]4n +3 = 10n +7[/tex]
With linear equations you should always begin by isolating the variable, getting it on one side of the equation by itself. You can do that in this scenario by subtracting 4n and 7 from both sides:
[tex]6n=-4[/tex]
Then you divide both sides by 6 to get:
[tex]-\frac{2}{3}[/tex]
