You need at least two expressions to find something in common between them. The GCF of 2x and 10 is 2.
Depending on the missing operational sign, that would be 2(x plus or minus 8)
3x + 2x - 8x + 2x = -x
4x2 - 12x + 9 = 4x2 - 6x - 6x + 9 = 2x(2x - 3) - 3(2x - 3) = (2x - 3)(2x - 3) or (2x - 3)2
-2x + 6 + 22 = -2x + 28
You can use them to find a variable. Lets say you have two equivalent expressions with the same variable... x + 2x - 42 = 0 2x - 28 = 0 If you combine these equivalent expressions you ahve... x + 2x - 42 = 2x - 28 In all of the expressions you have x = 7 There are also other applications but its confusing to explain.
Two linear expressions with a sum of -5x plus 4 are ( -5x + 4 ) and ( 4 - 5x).
It is: 2x(2x+11)
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
An expression does not equate to anything. An equation is equal to something. Expression: x+2 Equation: x+4=2x Equivalent expressions: x+2 and 2x-2 if x=4 Equivalent equations: x+4=2x and -x+10=2x if x=4
It means that two expressions represent the same number; for example, 5 is equivalent to 3 + 2. If there are variables in the expression, it means that the two expressions will evaluate to the same number, for any value assigned to the variable or variables. For example, for any value of x, 2x is the same as x + x; therefore, the two are equivalent.
Multiplication and addition.

4x plus 3 plus 2x is equivalent to expression 6x plus 3.
It is an expression.
Oh, what a happy little question! An equivalent expression for 6x plus 3 would be 3(2x + 1). You see, we're just factoring out a common factor of 3 from both terms to simplify it a bit. Just remember, there are many ways to express the same idea in math, just like there are many ways to paint a beautiful sky.
It is equivalent to 4x^2 +8xy
