Determine whether the equation is a linear equation..Help!
1. $\frac{x}{2} = 10 + \frac{2y}{3}$

2. $7n - 8m = 4 - 2m$

I guess both are linear, because

$\frac{x}{2} = 10 + \frac{2y}{3}$

$y = \frac{3}{2}(\frac{x}{2}-10)$

and

$7n - 8m = 4 - 2m$

6m = 4 - 7n

$m = \frac{4-7n}{6}$

This is a straight line, too
