Checking your answers for two-step linear equations is really simple! Here’s how to do it:
Solve the Equation: Start by solving the equation as usual. For example, if you have (2x + 3 = 11), you would first subtract 3 from both sides. Then, divide by 2.
Put the Value Back: Once you find out what (x) is, put that number back into the original equation. If you get (x = 4), you would replace (x) in (2(4) + 3).
Check the Sides: Do the math on both sides of the equation. The left side should be the same as the right side from the original equation. Here, (2(4) + 3 = 8 + 3 = 11), and that matches!
Doing this makes me feel sure that my answer is correct. Try it out yourself!
