<span>-3x + 2y = 2 eq (1)
7x - 3y = 7 eq (2)
Mutiply eq (1) by 3 and eq (2) by 2:
-9x + 6y = 6
14x - 6y = 14
Add th two new equations:
-9x + 14x = 6 + 14
=> 5x = 20
=> x = 20/5
=> x = 4
Now from eq (1)
-3(4) + 2y = 2
=> 2y = 2 + 12
=> 2y = 14
=> y = 14 / 2
=> y = 7
So the ordered pair is (4,7)
Answer: option B. (4,7)

Answer:
3x+13
Step-by-step explanation:
since all 4 sides of a square are same we can find the length by dividing the perimeter by 4:
(12x+52)/4=3x+13
3x+13
hope this helps
the sum of all the angles in a hexagon is 720°, so:
(4x-5)+117+(3x-3)+(3x+6)+118+(4x-3)=720
4x+3x+3x+4x= 720+5-117+3-6-118+3
14x=490
x= 490/14
x= 35
