Simplify the expression and solve.

  • {(2a³- 3b³ + 7) + (-a³ + b³ + 3ab - a​)} - {a³ + b³ - 3}
  • => {2a³- 3b³ + 7 - a³ + b³ + 3ab - a​} - a³ - b³ + 3
  • => {a³- 2b³ + 7 + 3ab - a​} - a³ - b³ + 3
  • => {a³- 2b³ + 7 + 3ab - a​} - a³ - b³ + 3
  • => -3b³ + 7 + 3ab - a​ + 3
  • => -3b³ + 10 + 3ab - a​

The solution to this algebraic problem is -3b³ + 10 + 3ab - a​.
