Welcome to friendly Math 101! Today's lesson is on how to check your answers when solving equations. To ensure correctness, substitute the solution back into the equation to create a true statement. For example, if x equals -3, substitute to get -3 * -3 + 4 = 13, which is true. However, if the solution is incorrect, it will create a false statement. For instance, if a equals 8 in a multi-step equation, substituting gives a false statement, indicating an incorrect solution. Always check your answers to ensure accuracy.

Check a Solution. 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.

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, its pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
Checking Solutions to Equations Check that the given number is a solution to the equation: Replace the variable in the equation with the given value, -1. 2 = 2 is a true statement. Check that the given number is a solution to the equation: Replace the variable in the equation with the given value, 3.
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.
There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.
