In mathematics, a two-step equation is an equation that requires two steps to solve. The first step is to isolate the variable on one side of the equation. The second step is to solve for the variable.
Checking your answer is an important step in solving any equation. To check your answer to a two-step equation, simply plug your answer back into the original equation. If the equation is true, then your answer is correct.
In mathematics, an equation is a statement that asserts the equality of two expressions. Equations with variables on both sides are equations in which the variable appears on both the left and right-hand sides of the equation. For example, the equation $$3x – 5 = 2x + 7$$ has the variable \(x\) on both sides of the equation.
Checking equations with variables on both sides is important because it allows us to determine whether a given value of the variable makes the equation true. To check an equation with variables on both sides, we can use the following steps:
Checking equations is a fundamental skill in mathematics and various scientific disciplines. It involves verifying the correctness and consistency of equations, ensuring that they accurately represent the relationships between variables and constants. The process of checking equations is crucial to avoid errors and ensure the reliability of mathematical models and scientific theories.
Checking equations holds paramount importance in scientific research, engineering design, and everyday problem-solving. Accurate equations form the backbone of calculations, predictions, and decision-making processes. Historically, the ability to check equations has been essential in advancing scientific knowledge and technological innovations.
