(10) When using substitution to solve this system of equations, what is the result of the first step? Eq#1 y = 6x + 3 Eq#2 x + 2y = 5

Answer 1

Given data:

The first equation given is y = 6x + 3.

The second equation given is x + 2y = 5​.

Subsitute (6x+3) for y in second equation.

$x+2(6x+3)=5$

Thus, the first option is correct.
