Answer:
7 - 16 = 9 x 4 = 36
Step-by-step explanation: 1 - 16 7 times. 9 + 9 + 9 + 9 = 36
14x + 10y = 72
14x + 4y = 96
6y = -24
6 6
y = -4
14x + 10y = 72
14x + 10(-4) = 72
14x - 40 = 72
+ 40 + 40
14x = 112
14 14
x = 8
(x, y) = (8, -4)
X + 13 = -4
x = -4 - 13
x = - 17
I am thinking it is the first one..solution is -17
