Yes

We have: #x + y = - 1# and #2 x + 5 y = 4# for #(- 3, 2)#

We can check whether this ordered pair satisfies the equations by substituting them into the respective equations:

#=> (- 3) + (2) = - 1#

#=> - 3 + 2 = - 1#

#=> - 1 = - 1#

and

#=> 2 (- 3) + 5 (2) = 4#

#=> - 6 + 10 = 4#

#=> 4 =4 #

Therefore, the ordered pair satisfies the equations.
