273x+1 = 9
33(3x+1) = 32
9x+3 = 2
9x = 2-3
9x = -1
x = -1/9
Check: 27(3*-1/9)+1 = 9
3x = 12 log3(12) = 2.261859507 x = 2.261859507
It is an equation ... Anything with an equals is an equation 2+b=6 Anything without an equals is an expression 2+a
That's an extraneous solution. You need to check for these when algebraically solving equations, especially when you take both sides of an equation to a power.
An equation.

Since the highest power of 'x' in the equation is '1', there's one solution.
3x = 12 log3(12) = 2.261859507 x = 2.261859507
It is an equation ... Anything with an equals is an equation 2+b=6 Anything without an equals is an expression 2+a

When the equation 2 raised to the power of log n is simplified, it equals n.
Assuming that the 2 in "5x2" is a power (5x2), then no, this is not a linear equation. It is a parabolic equation.
