Question

Which ecpression is the simplest form of 3(3x-4)-5(x+3)

Answer 1

`\\ \sf\longmapsto 3(3x-4)-5(x+3)`

`\\ \sf\longmapsto 9x-12-5x-15`

`\\ \sf\longmapsto 9x-5x-15-12`

`\\ \sf\longmapsto (9-5)x-27`

`\\ \sf\longmapsto 4x-27`

Answer 2

`\boxed{ \sf{Answer}}`

`\sf \: 3(3x - 4) - 5(x + 3) \\ \sf =( 3 * 3x) - (3 * 4) + ( - 5 * x) +( - 5 * 3 ) \\ \sf = 9x - 12 - 5x - 15 \\ \sf = 9x - 5x - 12 - 15 \\ = \underline{ \bf 4x - 27}`
