Question and answer
What are two symbolic techniques used to solve linear equations? Which do you feel is better? Explain why.
Elimination and substitution are two methods. If you readily see how to do the elimination, it is quicker. Substitution, however, [ is much more general and completely independent of immediate perception. So each technique has its own peculiar merit. Consequently, I doubt that there a single criterion that permits ranking. Just my opinion. Others may disagree; see what they say. ]

How many solutions does a system of linear equations in three variables have? Can systems of linear equations have infinitely many solutions? Under what circumstances could that occur?
Weegy: A system of linear equations means two or more linear equations. (In plain speak: 'two or more lines') If these two linear equations intersect, that point of intersection is called the solution to the system of linear equations. [ Systems of equations that have three variables are systems of planes. ] (More)

Identify four-steps to solving a linear system in three variables. Do these steps have to be done in a certain order? Are there any steps that could be skipped? Explain why or why not.
Weegy: Step 1: Isolate the x^2 and x terms. Use the addition and subtraction and isolate the x^2 and x terms on the left-hand side of the equation. [ [ Then, use the multiplication and division axioms to eliminate the coefficient from the x^2 term. Step 2: Make the coefficient on the x^2 term equal to 1. Use multiplication or division to eliminate the coefficient from the x^2 term. Step 3: Complete the square. To complete the square, take the coefficient of the x term, square it, and divide it by 4. Step 4: Solve the equation in step 3 by taking the square root of both sides of the equation. ] ] (More)

Do the equations x = 4y + 1 and x = 4y – 1 have the same solution? How might you explain your answer to someone who has not learned algebra?
Weegy: Yes. When you transfer things over the equal side it changes sides. (More)

The equations x = 4y + 1 and x = 4y – 1 will not have the same solutions. Think about it...is the solution of a number plus one the same solution of that same number minus one? That's like saying 2 - 1 = 1 and 2 + 1 = 1, the latter of which is clearly not a true statement. If they had the same solutions, meaning the same quantities of y, the x values would most definitely not be the same.
