Answer:
Option B is correct.
The best first step for solving the given system using substitution while avoiding fractions:
Solve for y in the first equation
Step-by-step explanation:
Given the system of equations:
[tex]3x+y=9[/tex] .....[1]
[tex]5x-3y = 1[/tex] .....[2]
We can write equation [1] as:
[tex]y = 9 -3x[/tex]
Using substitution substitute equation [tex]y = 9 -3x[/tex] into [2] we have;
[tex]5x-3(9-3x)= 1[/tex]
Therefore, the best first step for solving the given system using substitution while avoiding fractions is:
Solve for y in the first equation.
