Answer:
Simplified: -4a²b²+18a³-2b³
3a(6a²-4ab²)+8a²b²-2b³
Multiply 3a by 6a² and-4ab²
18a³-12a²b²+8a²b²-2b³
combine like terms (-12a²b² and 8a²b²)
-4a²b²+18a³-2b³
Hope this helps
Step-by-step explanation:
3(x - 3) + 2x + 9 - 2x + 2(x - 1)
3x - 9 + 2x + 9 - 2x + 2x - 2
Solving like terms
5x - 2
5x = 2
x = 2/ 5
I think she incorrectly applied the multiplication and division properties of equality
