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 + 4y = −9
2x + 5y = −6 (6 points)
2x + 5(4y − 9) = −6
2x + 5(−4y − 9) = −6
2(4y − 9) + 5y = −6
2(−4y − 9) + 5y = −6

how can one half x − 5 = one third x + 6 be set up as a system of equations? (6 points)
a) 2y + x = −10
3y + x = 18
b)2y + 2x = −10
3y + 3x = 18
c) 2y − x = −10
3y − x = 18
d)2y − 2x = −10
3y − 3x = 18
