7x-3(5x+2)-6(7+2x)

Answer 1

-20x-48

Explanation:

7x-(15x +6)-6(7+2x)

7x-(15x+6)-(42+12x)

7x-15x-6-42-12x

(7x -15x-12x)+(-6-42)

=-20x-48

Answer 2

-20x - 48

Explanation:

7x - 3(5x +2) - 6*(7 + 2x) = 7x + (-3)*5x + (-3)*2 + (-6)*7 + (-6)*2x

= 7x - 15x - 6 - 42 - 12x

= 7x - 15x - 12x - 6 -42 {Combine like terms}

= -20x - 48
