Question

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

Answer 1

$\boxed{ \sf{Answer}}$

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

Answer 2

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

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

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

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

$\\ \sf\longmapsto 4x-27$
