Question

b) 87-(41+y)=22
a) (x-87)-27=36

Answer 1

b) 87-(41+у)=22
87-41-у =22
-у = 22-87+41
-у = -24
у = 24
a) (x-87)-27 = 36
x-87-27 = 36
x = 36+87+27
x = 150

Answer 2

пожалуйста)

Answer 3

а) (x-87)-27=36. x-87-27=36. x-87=36+27. x-87=63. x=63+87. x=150. Ответ:x=150. b) 81-(41+y)=22. 81-41-y=22. 41-y=22-81. 41-y=-59. y=-59-41. y=-100. Ответ: y=-100.
