An equation with two equal signs is really to explicit equations (or three implicit ones). For example, expession 1 = expression 2 = expression 3 is equivalent to expression 1 = expression 2 AND expression 2 = expression 3 and, by transitivity, expression 1 = expression 3 So you need to solve two of the above three.
Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)
Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)
An expression does not include an equals sign (=) For eg: 2x+3 would not be an equation but an expression However, 2x+3=0, is definitely an equation with a solution x= -3/2. An expression does not have a definite solution. An expression is a set of terms with mathematical operations combining them. An equation consists of two expressions with an equals sign between them. An expression is a collection of terms and does not have an = sign An equation is a collection of terms but has an = sign between them.
They are terms of some kind of an algebraic expression and without an equality sign it is not an equation.
i dont understand what you mean by symbolic but ill just do an example 2a + 3 = 4 - 5a first collect like terms 2a +3 -3 = 4 -3 -5a 2a = 4-3 - 5a 2a + 5a = 1 - 5a + 5a 2a + 5a = 1 7a = 1 divide both sides by the coefficient of the unknwown(i.e. the number in front of the letter) 7a/7 = 1/7 a = 1/7

Answer to: 5a + 1 = a - 3a = -1
The question contains an expression - not an equation nor an inequality. An expression cannot be true or false.
5a + 3 + (2a - 2) + a= 5a + 3 + 2a - 2 + a= 8a + 1
We're not sure what the question means by "root". It may be what's usuallyreferred to as the "solution" of the equation ... the number that 'a' must be inorder to make the equation a true statement. Here's how to find the 'solution':- 5a - 3 = 3aAdd 5a to each side:- 3 = 8aDivide each side by 8:- 3/8 = a
3

In a mathematical sense, 3x isn't an equation, but an expression. In this expression, 3 is a coefficnet.
m2 (-1-3) is an expression, neither an equation nor an inequality. Therefpore, there is nothing to solve.
