Answer:
x = 27
Step-by-step explanation:
First of all the equation written on the question is incorrect, like not the image, this is because the angle of 3x + 10 and 3x - 28 is not the same, The equation will be 3x + 10 + 3x - 28 = 180
=> 6x - 18 = 180
=> 6x = 180 - 18
=> 6x = 162
=> x = 162 / 6
=> x = 27
Hope it helps :) If I am wrong, please consider telling me......
Required number = 1/2 (2/7 + 3/4)
= 1/2 ((8 + 21)/28)
= {1/2 × 29/28)
= 29/56
Hence, 29/56 is a rational number lying halfway between 2/7 and 3/4.
<span>A) -12x - y = 6
</span><span>
B) 17x + y = 4
</span>Adding both equations:
5x = 10
x = 2
Since x =2
<span>17x + y = 4
</span>
17 * 2 + y = 4
y = 4 -34
y = -30
