20 + 17y = -6 + 15y
First, regroup your terms.
Second, take away '15y' from each side.
Third, subtract '17y - 15y' to get '2y'.
Fourth, take away '20' from both sides.
Fifth, simplify '-6 - 20' to get '-26'.
Sixth, divide both sides by '2'.
Seventh, how many times goes 2 go into 26? 26 ÷ 2 = 13.

Answer:
y = -13

Theorem
The measure of an exterior angle of a triangle equals the sum of measures of the remote interior angles.
Angle STV is an exterior angle of triangle SRT.
The two remote interior angles to exterior angle STV are angles S and R.
Since the triangle is isosceles, with sides ST and TR equal, angles S and R are equal, so they both measure 27 deg.
<STV = 27 + 27
<STV = 54
A. The number of 10-boards Peter bought is equal to n divided by 10. Then, each of the 10-boxes will get two boxes of nails. The number of boxes of nails that Peter will have after buying n boards will be,
N = (2)(n/10)
Simplifying,
<em> N = n/5</em>
b. If the number of boards are 90 then,
N2 = (90/10)(2)(100 nails/box)
N2 = 1800
Answer: 1800
The answer to that is x=8
