The result 0.14 as percentage is 14%
Margin error is 38% ⁺/₋ 14%
Answer:
The system of equations has no solution.
Step-by-step explanation:
Given the system of equations
2y = 2x+7
x = y+2
solving the system of equations

Arrange equation variables for elimination

Multiply -y+x=2 by 2: -2y+2x=4

so adding




so the system of equations becomes

0 = 11 is false, therefore the system of equations has no solution.
Thus,
No Solution!
If he buys x pens and y pencils
3x + y = 10
x ≤ y
You draw the line 3x + y = 10 .<span>(it passes by (0,10) and (-10/3,0)
</span>
<span>You Draw the line y=x [it passes by (0,0), (1,1), (2,2)]
</span>
<span>Solution: is the points with integer x and y, that belong to the segment of the
line 3x +y = 10 between the x-axis and the line y=x. Those points are
(1,7) , (2,4), (3, 1).
