Solution:
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.
