5x-3=21-x
6x=24
X=4
You simply have to isolate the variable and then divide by 6 so that x is completely alone.
Answer:
<em>start with y</em>
y
<em>add 7</em>
y+7
<em>multiply by 3</em>
3(y+7)
<em>subtract 6</em>
3(y+7)-6
<u>therefore the answer is:</u>
3y + 21 - 6
=
3y + 15 or 3(y+5)

If you meant that the perimeter (not permitter) of a square is 12 units, then the length of one side (not silence) of the rectangle is (12 units)/4 = 3 units.
From the given figure, it can be seen that 13x = 15x - 8 because they are vertical angles and thus are equal.
13x = 15x - 8
15x - 13x = 8
2x = 8
x = 8/2 = 4
Thus, 15x - 8 = 15(4) - 8 = 60 - 8 = 52.
RT is a diameter, which means that mRT = 180
mRV + mVU + 52 = 180
mRV + mVU = 180 - 52 = 128
Now, given that mRV = mVU,
Thus, 2mVU = 128
Therefore, mVU = 128 / 2 = 64°
