Answer:

An algebraic expression is a <em>mathematical expression</em> that contains constants and/or variables that can be expressed using letters and/or numbers.

For example, the following expressions are algebraic:

2x + 4 = 5 (Where 'x' is a variable)
2x + a = 3 (Where 'x' is a variable and 'a' a constant)
a + bx + cy = 1 (Where 'x' and 'y' are variables and 'a', 'b' and 'c' are constants).

The following are NOT algebraic expressions

Answer:

$\large\boxed{x=\dfrac{4}{3}=1\dfrac{1}{3}}$

Step-by-step explanation:

$x-\dfrac{2}{3}+\dfrac{1}{6}=\dfrac{5}{6}\qquad\text{multiply both sides by 6}\\\\6x-6\!\!\!\!\diagup^2\cdot\left(\dfrac{2}{3\!\!\!\!\diagup_1}\right)+6\!\!\!\!\diagup^1\cdot\left(\dfrac{1}{6\!\!\!\!\diagup_1}\right)=6\!\!\!\!\diagup^1\cdot\left(\dfrac{5}{6\!\!\!\!\diagup_1}\right)\\\\6x-(2)(2)+1=5\\\\6x-4+1=5\\\\6x-3=5\qquad\text{add 3 to both sides}\\\\6x=8\qquad\text{divide both sides by 6}\\\\x=\dfrac{8}{6}\\\\x=\dfrac{8:2}{6:2}\\\\x=\dfrac{4}{3}$
