Fix Equation Attestation For Free

A mathematical proof is an inferential argument for a mathematical statement, showing that the stated assumptions logically guarantee the conclusion.

The value of the variable which makes the equation a true statement is the solution of the equation. So, x = 3 is the solution of an equation 4x ? 8 = ?5 + 3x.

A General Rule for Solving Equations Simplify each side of the equation by removing parentheses and combining like terms. Use addition or subtraction to isolate the variable term on one side of the equation. Use multiplication or division to solve for the variable.

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.

Initial Definition. Verifying a solution ensures the solution satisfies any equation or inequality by using substitution. Example One. Verify whether or not x = 3 is a solution to the conditional equation 2x - 3 = 6 - x. Substitute x = 3 into 2x - 3 = 6 - x to see if a true or false statement results.

A solution to an algebra problem is valid if both sides of the equation are still equal when the problem has been worked out with the chosen solution substituted for the variable(s). Verifying solutions is a good way to double-check the work on any problem.

Here are some things we can do: Add or Subtract the same value from both sides. Clear out any fractions by Multiplying every term by the bottom parts. Divide every term by the same nonzero value. Combine Like Terms. Factoring. Expanding (the opposite of factoring) may also help.

The process of making sure a solution is correct by making sure it satisfies any and all equations and/or inequalities in a problem. 1. Example: Verify that x = 3 is a solution of the equation x2 ? 5x + 6 = 0.
