Question

Which step should always be performed first when preparing to use the elimination method on a pair of linear equations?

Accepted Answer

Write both equations in standard form so x and y terms and the constants are aligned vertically.

Answer

Multiply both equations by their leading coefficients to create large integers that make elimination obvious.

Answer

Immediately isolate a variable in both equations to perform substitution rather than elimination.

Answer

Graph both equations first to determine the exact point of intersection before doing any algebraic manipulation.
