Answer:
A
Step-by-step explanation:
(x, y)
Left and right affects the x, up and down affects the y.
Since it's a positive 4, it goes up. We can eliminate B and D.
Since it's a positive 8, it goes right. A.
X=102 y=288 =390
X=50+32=82=180-82=102
Y= 50+32=82=360-82=288
Total answer is =390
X = 16
there you go
12
2x - 7 =5 +x
2x - x =5 +7
x =12 (one solution)
