Question

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 second equation is substituted into the first equation.

4x – 3y = –6
–x – 5y = –9

anonymous · Answer

4x – 3(–5y + 9) = –6
		4(–5y + 9) – 3y = –6
		4x – 3(5y – 9) = –6
		4(5y – 9) – 3y = –6
