How many solutions exist for the system of equations below? 3x+y=18 3x+y=16
2 answers:
<span>A) 3x+y=18
B) 3x+y=16
These equations are inconsistent and have no solutions. If these equations were graphed, it would be two parallel lines.
</span>
we have
-------> equation 
solve for y
The slope 
-------> equation 
solve for y
The slope 
The two slopes are the same, so the lines are parallel.
therefore
It's an inconsistent system of equations that has no solution.
<u>the answer is</u>
The system has no solution

Answer:
x = 3.5.
Step-by-step explanation:
This is an equilateral triangle ( as all angles = 60 degrees) so all 3 sides are of equal length.
Thus 2x - 3 = 4
2x = 7
x = 3.5.
