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