Question

(5x3-6x2)x( 2x4+3)-(9-7)x(8:2-2+9)

Answer 1

(5x3-6x2) x (2x4+3) - (9-7) x (8:2-2+9) = ? 

(15-12) x ( 8+3) - 2 x (4-2+9) = ? 
3 x 11 - 2 x 11 = ? 
= 33 - 22
=11 

Answer 2

$(5 \times 3 -6 \times 2) \times (2 \times 4+3)-(9-7) \times (8:2-2+9)= \\ =(15-12) \times (8+3)-2 \times (4-2+9)= \\ =3 \times 11-2 \times (2+9)= \\ =3 \times 11-2 \times 11= \\ =33-22= \\ =11$
