Answer 1

Solve for y in first equations

Answer 2

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:

$3x+y=9$         .....[1]

$5x-3y = 1$       .....[2]

We can write equation [1] as:

$y = 9 -3x$

Using substitution substitute equation $y = 9 -3x$ into [2] we have;

$5x-3(9-3x)= 1$

Therefore, the best first step for solving the given system using substitution while avoiding fractions is:

Solve for y in the first equation.
