Question

Simplify 4+5(3x - 2) - 3x

Answer 1

12x - 6

Explanation:

`\rm \: 4 + 5(3x - 2) - 3x`

`\rm \: = 4 + 15x - 10 - 3x \: \sf (distribute \: the \: 5)`

`\rm= 12x - 6 \: \sf (combine \: like \: terms)`

`\rm= 6(2x - 1) \: \sf (factor \: out \: a \: 6)`

`\rm \: = 6(2x) - 6(1) \: \sf (distribute \: the \: 6)`

`\rm \:= 12x - 6 \: \sf (simplify)`
