Answer: A) 3(10 - 5y) + 6y =12
Step-by-step explanation:
As per the question , the given system of linear equation :
Here , To solve the system of equations using substitution , Johanna isolates x in the second equation and writes
As per the substitution method , the next step is to substitute the isolated value of 'x' in first equation , thus the next step will become
Hence, the correct option is A) 3(10 - 5y) + 6y =12
Kilo = 1,000
