Does everyone use algebra?
YES!! You use algebra in your everyday lives. Adding is considered an equation. An equation is a problem with an equal sign. An expression has no answer (an equal sign).
Can someone Simplify the expression 2x - 8 - -4x plus 3?
Assuming that your equation is:_2X - 8 = -4X +3, adding 8 to both sides gives,2X = -4X + 3 +8, gives2X = -4X +11, then adding 4X to both sides,6X = 11 which gives X = 11/6 = 1.83333.your original equation was NOT an equation - that is an expression where two things were equal to each other.
Does adding the same nonzero number to the numerator and denominator of a fraction produce an equivalent fraction?
No because the numerator and the denominator must be multiplied or divided by the same number for a given equivalent fraction
Can a algebraic expression have more than one operation?
Yes. In general, you can combine expressions into more complicated expressions. For example, adding an expression to another expression will, again, yield an expression.
How does an expression of addition change to subtraction?
Adding +k is the same as subtracting (-k).

How can you solve an equation to get an equivalent equation?
In general, if you apply the same operation to both sides of an equation, you get an equivalent equation - at least if you do simple things like adding, subtracting, multiplying by a non-zero number, and dividing by some number.

How do you find the value of x when there is no equal sign in the equation?
You cannot explicitly find the value of x without an equal sign, as an equation without an equals sign is an algebraic expression. However, we can turn your expression into an equation by adding in an equals sign, but setting the value to a variable. For example, 2x+5=y, or 5x2-4x=y. You can solve for x like that. The phrase "... there is no equal sign in the equation ..." is a meaningless description. Without an 'equal' sign, there is no equation.
What are the rules in transposition of terms in equation?
A term may be moved from one side of an equation to the other if the sign of the term in changed from plus to minus or vice versa after the move. Note that this follows from the more basic rule that an equation is not changed by adding the same term to each side. Transposing a term and changing its sign is equivalent to adding the positive/negative counterpart of the term to be transposed to each side of the equation.

What is an algebraic expression with the variable x that has a value of 3 when evaluated?
A solution for x in an algebraic expression where the result is 3 might be for example, 4 - x = 1. You can solve by adding "x" to each side of the equation (4 = 1 + x) then subtracting 1 from both sides (3 = x, or x=3).
The elimination method is useful when you can eliminate one of the variable terms from an equation by adding or subtracting another equation?
True
How does an expression of addition change to subtraction?
Adding +k is the same as subtracting (-k).
