Answer:y1 = 0.9, y2 = 1.4

Step-by-step explanation:Answer:The set

[tex]y=log_3 (5x)[/tex]

[tex]y=log_5 (2x+3)[/tex]

Step-by-step explanation:We separate the left and right side of the equation, to create two new equations:

(1) [tex]y=log_3 (5x)[/tex]

(2). [tex]y=log_5 (2x+3)[/tex]

and then to solve Tanisha’s original equation, we find the solution to the system that we got above.

The first step in solving the above system of equations is to take the value for [tex]y[/tex] from

equation(1),and substitute it intoequation(2)which gives us:[tex]y=log_5 (2x+3)\\\\ \boxed{log_3(5x) = log_5 (2x+3)}[/tex]

which is the same equation that Tanisha set out to solve.
