\\ \rm\rightarrowtail 3-2a<13


\\ \rm\rightarrowtail -2a<10


\\ \rm\rightarrowtail -a<5


\\ \rm\rightarrowtail a>-5

And


\\ \rm\rightarrowtail 5a<17


\\ \rm\rightarrowtail a<17/5


\\ \rm\rightarrowtail a<3(2)/(5)

So

solution set


\\ \rm\rightarrowtail a\in\left(-5,3(2)/(5)\right)

So

  • a={-4,-3,-2,-1,0,1,2,3}

Answer:

  • {- 4, - 3, -2, -1, 0, 1, 2, 3}

Explanation:

Solve each inequality in the system:

  • 3 - 2a < 13 2a > 3 - 13 2a > - 10 ⇒ a > - 5
  • 5a < 17 ⇒ a < 17/5 ⇒ a < 3.4

The solution is:

  • - 5 < a < 3.4

The integer solution set is:

  • {- 4, - 3, -2, -1, 0, 1, 2, 3}
