Question

What would be the most appropriate first step if you wanted to solve this system of equations using elimination? 3x+2y=7 x+4y=−8 A. Multiply the first equation by −1 B. Multiply the second equation by −2 C. Multiply the first equation by −2 D. Multiply the second equation by -1−1

Answer 1

A. Multiply the first equation by −1

Explanation:

From the above question, our system of equations is

3x+2y=7... Equation 1

x+4y=−8..... Equation 2

Hence, solving by Elimination, the first step would be if we are eliminating x first, we are to Multiply Equation 1 by -1

Option A is the correct option
