Answer: 15.8 .
Step-by-step explanation:
2 x { 6 + [ 12 ÷ (3 + 2)]} - 1 ;
= 2 x { 6 + [ 12 ÷ (5)]} - 1 ;
= 2 x { 6 + [ 12/5 } - 1 ;
= 2 x { 6 + [ 2.4 ] - 1 ;
= 2 x { 8.4] - 1 ;
= (2 * 8.4) - 1 ;
= 16.8 - 1 ;
= 15.8 .

Expand out, this literally just wants you to multiply everything by -1.
so 7*-1 = -7
-c*-1 = c
thus putting them together to get -7+c which is just c-7
