Beyond the Answer
To correctly use the elimination method in solving the system of equations, Stacy needs to manipulate one of the equations to match the coefficients of either
or
for easy elimination.
For instance, if Stacy multiplies the first equation
by -2, she will rewrite it as
. This modified equation can then be paired with the second equation
to eliminate the variable
by adding the two equations together.
Moreover, it’s crucial for students to double-check their modifications to ensure correctness. They might mistakenly alter coefficients or constants, leading to incorrect elimination or false solutions! It’s a great reminder to keep an eye on negative signs during these transformations.
