### Collecting like terms

After brackets have been expanded, the like terms can be collected.

#### Example 5

Expand the brackets and collect like terms.

- \(2(x-6) + 5x\)
- \(3 + 3(x-1)\)
- \(3(2x + 4) + 6(x-1)\)

#### Solution

- \(2(x-6)+5x=2x-12+5x=7x-12\)
- \(3+3(x-1)=3+3x-3=3x\)
- \(3(2x+4)+6(x-1)=6x+12+6x-6=12x+6\)
