We check a solution to an equation by replacing the variable in the equation with the value of the solution. A solution should result in a true statement when simplified.
How do I know if my math is correct?
The method works like this: For any addition or multiplication problem, take the digits of each number you’re adding or multiplying and add them together. So for instance, if we were adding 218 and 435, we would add 2+1+8=11, and 4+3+5=12. Then, if we get a two-digit answer we’d repeat the process.

What are examples of algebraic equations?
Algebraic equation, statement of the equality of two expressions formulated by applying to a set of variables the algebraic operations, namely, addition, subtraction, multiplication, division, raising to a power, and extraction of a root. Examples are x 3 + 1 and (y 4x 2 + 2xy – y)/(x – 1) = 12.
How do you do algebraic equations?
Solve a two step equation by multiplying at the end instead of dividing. The principle for solving this type of equation is the same: use arithmetic to combine the constants, isolate the variable term, and then isolate the variable without the term. Let’s say you’re working with the equation x/5 + 7 = -3.
What is a simple equation in Algebra?
An equation is two expressions on either side of a sign that indicates their relationship. That relationship may be equals (=), less than (<) or greater than (>), or some combination (for example, less than or equals to <=). Simple equations therefore include 2 + 2 = 4 and 5 + 3 > 3 + 4.
How do you solve algebra problems?
Solving Problems Recognize that algebra is just like solving a puzzle. Perform operations on both sides of the equation. Isolate the variable on one side of the equation. Take the root of the number to cancel an exponent. Combine like terms. Practice with more complex problems. Check your answers.
