Step-by-step explanation:
The students should prepare a Trapezoid parallelogram. A Trapezoid is a parallelogram who has a both side that is parallel to each other but cannot be in the same size but if they are not parallel to each other, both side length should be the same. So they have to create a trapezoid whose one side is 10 cm and an angle of 50 degrees

First, let's multiply the first equation by two on the both sides:
<span>8x + 7y = 39 /2
</span>⇒ 16x + 14y = 78
Now, the system is:
<span>16x + 14y = 78
</span><span>4x – 14y = –68
</span>
After adding this up in the column:
(16x + 4x) + (14y - 14y) = 78 - 68
20x = 10
⇒ x = 10/20 = 1/2
y can be calculated by replacin the x:
<span>8x + 7y = 39
</span>⇒ 8 · 1/2 + 7y = 39
4 + 7y = 39
7y = 39 - 4
7y = 35
⇒ y = 35 ÷ 7 = 5
