SOLUTION:
[2(y + 5) - 5] + 9 = 5(y - 1)]
[2y + 10 - 5] + 9 = 5y - 5
[2y + 5] + 9 = 5y - 5
2y + 14 = 5y - 5
-5y + 2y = -14 - 5
-3y = -19
[tex]\frac{-3y}{-3}[/tex] = [tex]\frac{-19}{-3}[/tex]
y = [tex]\frac{19}{3}[/tex] or [tex]6\frac{1}{3}[/tex] or 6.33
CHECK:
[2(y + 5) - 5] + 9 = 5(y - 1)]
[2([tex](\frac{19}{3})[/tex] + 5) - 5] + 9 = 5([tex](\frac{19}{3})[/tex] - 1)]
[2([tex]\frac{34}{3}[/tex]) - 5] + 9 = 5([tex]\frac{16}{3})[/tex]
[[tex](\frac{68}{3})[/tex] - 5] + 9 = [tex]\frac{80}{3}[/tex]
[tex]\frac{53}{3}[/tex] + 9 = [tex]\frac{80}{3}[/tex]
[tex]\frac{80}{3}[/tex] = [tex]\frac{80}{3}[/tex]
TRUE
ANSWER: [tex]\frac{19}{3}[/tex]
