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 first equation is substituted into the second equation.

-x + 5y = 1
2x + 4y = -4

2(-5y + 1) + 4y = -4
2x + 4(-5y + 1) = -4
2x + 4(5y - 1) = -4
2(5y - 1) + 4y = -4

Answer 1

-x+5y=1
5y=1+x
5y-1=x

Therefore 2(5y-1)+4y=-4 is the equation
