Answer 1

5(2x+3)-4(7x-4)+3(6x-5)
5(6)-4(-28)+3(-30)
30+112-90=
52

Answer 2

Respuesta:

5(2x + 3) - 4(7x - 4) + 3(6x - 5)​

5(2x + 3) = 10x + 15

10x + 15 - 4(7x - 4) + 3(6x - 5)

-4(7x - 4) = -28x + 16

10x + 15 - 28x + 16 + 3(6x - 5)

3(6x - 5) = 18x - 15

10x + 15 - 28x + 16 + 18x - 15

$\boxed{16}$
