Answer:
The best first step for solving the given system using substitution is substitute the value of -9x from equation 1 in equation 2
Step-by-step explanation:
Given :
To Find: What is the best first step for solving the given system using substitution?
Solution:
--1
--2
Since we are supposed to solve these equations using substitution method
So, the first best step for solving the equation is :
Both the equations contains -9x
So, substitute the value of -9x from equation 1 in equation 2
Substitute the value of y in 1 to get value of x
So,
Thus the solution is (2,7)
Hence the best first step for solving the given system using substitution is substitute the value of -9x from equation 1 in equation 2
