34 times 4 using partial products is equal to 136. First, you have to multiply 30 by 4 and that product is 120 and after, you have to multiply 4 by 4 and that is equal to 16. Last, add the two products together and you get 136.
-x - 7y = 9
-x + 9y = -23
=====
-7y - 9y = 9 - (-23)
-16y = 32
y = -2
===
-x -7*(-2) = 9
-x + 14 = 9
-x = 9 - 14
-x = -6
x = 6
(6 ; -2)
