Given the following system of equations:

3x + 5y = 30
x + 3y = 10

which action creates an equivalent system that will eliminate one variable when they are combined?

a. multiply the second equation by βˆ’1 to get βˆ’x βˆ’ 3y = βˆ’10.
b. multiply the second equation by βˆ’3 to get βˆ’3x βˆ’ 9y = βˆ’30.
c. multiply the first equation by βˆ’1 to get βˆ’3x βˆ’ 5y = βˆ’30.
d. multiply the first equation by βˆ’3 to get βˆ’9x βˆ’ 15y = βˆ’90.
