c

anonymous · Answer

and can you help me with some others after this

anonymous · Answer

ok thanks

anonymous · Answer

If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to x from the first equation is substituted into the second equation.

x - 6y = -15
x - 3y = -3

anonymous · Answer

a. x - 3(6y - 15) = -3	
	 b. x - 3(-6y - 15) = -3	
	 c. (6y - 15) - 3y = -3	
	 d. (-6y - 15) - 3y = -3

kamille · Answer

Well, do you know what "substitution" method means?
