Answer 1

11) 987 - (x+364) = 519              

987 - x - 364 = 519

623 - x = 519

- x = 519 - 623

- x = - 104

x = 104

12) 3128 - (m+425) = 1509

3128 - m - 425 = 1509

2703 - m = 1509

- m = 1509 - 2703

- m = - 1194

m = 1194

Answer 2

11) 987-(x+364)=519

987-x-364=519

-x=519-987+364

-x=-104

x=104

12) 3128-(m+425)=1509

3128-m-425=1509

-m=1509-3128+425

-m=-1194

m=1194
