2. (06.01) If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to y from the first equation is substituted into the second equation. 15x − y = −6 5x − 3y = −13 (1 point) 5(−15x − 6) − 3y = −13 5(15x + 6) − 3y = −13 5x − 3(15x + 6) = −13 5x − 3(−15x − 6) = −13

15x - y = -6......15x + 6 = y...now we sub this into the other equation and get :

5x - 3y = -13.....
5x - 3(15x + 6) = -13 <===

Answer:

[tex]5x - 3(15x+6)= -13[/tex]

Step-by-step explanation:

[tex]15x - y = -6[/tex]

[tex]5x - 3y = -13[/tex]

Lets solve the first equation for y

[tex]15x - y = -6[/tex]

Subtract 15x on both sides

[tex]-y =-15x-6[/tex]

Divide by [tex]-1[/tex] on both sides

[tex]y =15x+6[/tex]

now substitute y in the second equation

[tex]5x - 3y = -13[/tex]

[tex]5x - 3(15x+6)= -13[/tex]
