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 + 2y = 4
x – 5y = 11

anonymous · Answer

solve first equation for x
x=4-2y
sub into second equation 
4-2y-5y=11  
(or it might look like this -2y+4-5y=11)
