To check if the answers to linear equations are correct, we can use a simple method called substitution. Let me break it down for you!
Solve the Equation: First, we need to find the value of the variable. For example, if we have the equation (2x + 4 = 10), we can figure out that (x = 3).
Substitute Back: Now, we take that value we just found and put it back into the original equation. For our example, we check: (2(3) + 4 = 10).
Verify: Finally, we see if both sides of the equation are equal. If they are, then we know we did it right! In our case, (6 + 4 = 10) is true, so (x = 3) is correct.
Using substitution is a great way to make sure our answers are right!
