This is solved by breaking the equasion down.

2 { 5 [12 + 5 (500 - 100) + 399 ]}

2 { 5 [12 + 5 (400) + 399]}

2 { 5 [12 + 2000 + 399]}

2 { 5 [2411]}

2 {12055}

24110

Is this the answer you were looking for?
2(5(12+5(500−100)+399))

=2(5(12+(5)(400)+399))

=2(5(12+2000+399))

=2(5(2012+399))

=2(5)(2411)

=(2)(12055)

=24110

good job
