If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to y from the first equation is substituted into the second equation. 15x βˆ’ y = βˆ’6 5x βˆ’ 3y = βˆ’13 5(βˆ’15x βˆ’ 6) βˆ’ 3y = βˆ’13 5(15x + 6) βˆ’ 3y = βˆ’13 5x βˆ’ 3(15x + 6) = βˆ’13 5x βˆ’ 3(βˆ’15x βˆ’ 6) = βˆ’13
