Question

X + 6y = 2 4x - 3y = 10 Pick the first step to solving this system of equations using the addition method.

Answer 1

x + 6y = 2
4x - 3y = 10

The first thing to do when solving a system of equations using the addition/elimination method is to multiply one or both of the equation by a value that will cancel out one of the variable terms. 

Based on this, the correct answer is D - multiply the bottom equation by 2 thus eliminating the y variable when the equations are added together:

x + 6y = 2                     x + 6y = 2
2(4x - 3y = 10)    -->    8x - 6y = 20

Hope this helps.
