The first one is NOT equivalent
❌ 8 - 4( -2.2x + 1.1 ) = 8.8x + 12.4
The second one IS equivalent
✅ 7x -2(1.3x + 3.5) = 4.4x -7
Step by step
8 - 4( -2.2x + 1.1 ) = 8.8x + 12.4
Distribute
8 + 4.4x - 4.4 = 8.8x + 12.4
4.4x + 3.6 = 8.8x + 12.4
❌Not equal
7x -2(1.3x + 3.5) = 4.4x -7
7x -2.6x -7 = 4.4x -7
4.4x -7 = 4.4x -7
✅This is equivalent!
