Question

what is the first step in solving systems of equations using the elimination method? constants substitute one variable into the other equation multiply both equations by the same number graph both equations on a coordinate plane

Explanation:

The elimination method aims to remove one variable by making coefficients of a variable opposites. First, you may need to scale equations so a variable's coefficients cancel when equations are combined. Substitution is a different method, graphing is a separate approach, and "constants" is incomplete/incorrect.

Answer:

Multiply both equations by the same number
