"When using the substitution method, how do you choose which variable to isolate first? Take this system. 8x plus y equals negative 11, and 2x squared equals y plus 341. The speed trap is trying to isolate x. That creates an ugly fraction that makes your next step a nightmare. Instead, find the variable that appears without an exponent in both equations. Here, that's y. Isolate it on both sides to get these two flat equations. Because you prioritize the winnier variable, you skip the fractions completely, and move everything to one side to combine like terms. This gives you an equation with massive, intimidating numbers. But don't panic. Just divide the entire equation by 2 to shrink the coefficients. Now it's much easier to factor, revealing your two possible roots, negative 15 and 11. Because you kept the algebra flat and avoided messy squares, you can instantly match negative 15 to the correct option and move on in seconds."
