<span>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:
</span>x + 6y = 2 x + 6y = 2
2(4x - 3y = 10) --> 8x - 6y = 20<span>
Hope this helps.</span>
4x+10y=<span>10

Answer:
96
Step-by-step explanation:
For each of the 4 items in the first column, Dave can choose any of the 6 items in the second column.
For each of those 4×6 = 24 combinations of items, Dave can choose any of the 4 items in the third column.
The total number of choices Dave can make is ...
