Answer:

Option C - Multiply the 1st equation by 2

Step-by-step explanation:

To find : Which step could be completed in order to prepare the system of equations below for the elimination method?

Solution :

1st equation: 5x-3y=10

2nd equation: 8x+6y=15

For elimination method,

We eliminate the y by multiplying 1st equation by 2 and add by 2nd equation.

i.e. 1st equation became  10x-6y=20

Add with 2nd equation,

10x-6y+8x+6y=20+15

18x=35

x=\frac{35}{18}

Substitute in (1),

5(\frac{35}{18})-3y=10

\frac{175}{18}-3y=10

3y=\frac{175}{18}-10

3y=\frac{175-180}{18}

3y=\frac{-5}{18}

y=\frac{-5}{54}

Therefore, the step  could be completed in order to prepare the system of equations below for the elimination method is option C.
