Answer:

$x = 3$

Step-by-step explanation:

$x + 6 = 2x + 3 \\ subtract \: 2x \: from \: both \: sides \\ \\ -1x + 6 = 3 \\ subtract \: 6 \: from \: both \: sides \\ \\ - 1x = - 3 \\ divide \: both \: sides \: by \: - 1 \\ \\ x = 3$

Answer:

Step-by-step explanation:

x + 6= 2x + 3

what you would do to find the answer is first subtract the coeffcient 2 on both sides of the equation. ( Subtract the 2 under 2x for the right side of the equation and subtract 2 under the x on the left side. ) Then you would subtract 6 on both sides. (subtract 6 under the 6 on the left side of the equation and subtract 6 under the number 3 on the right side of the equation)

so that would give you -x = -3 However you would have to eliminate the x on the right side of the equation and so you would divide positive x (also known as 1x) on both sides. -1x/-1 = -1 and -3/-1 = 3

Answer:

3rd quadrant

Step-by-step explanation:

First we just convert the angle from radians to degrees
$\frac{31\pi radians }{6}*\frac{180degrees}{\pi radians} =\frac{31*180}{6} degrees=930degrees$
Now that's too big, all this means is if we start rotating from the positive y-axis in a circle we will cross the starting point 2 times, 2 full circles;
$930degrees-360degrees=570degrees\\570degrees-360degrees=210degrees$
Now in which quadrant it 210 degrees?
0 degrees to 90 degrees is 1st quadrant
90 degrees to 180 degrees is 2nd quadrant
180 degrees to 270 degrees is 3rd quadrant
270 degrees to 360 degrees is 4th quadrant
So our answer is the 3rd quadrant.
