Question

а) (x-87)-27=36 б) 87-(41-y)=22 реши уравнение и выполните проверку

Answer 1

$(x - 87) - 27 = 36 = 114x + 36 = 150x$

Answer 2

(x-87)-27=36
x-87=36+27
x-87=63
x=63+87
x=150
(150-87)-27=36
63-27=36
36=36
б)87-(41-y)=22
87-41+y=22
87+y=22+41
87+y=63
y=63-87
y=-24
87-(41-(-24)=22
87-(41+24)=22
87-65=22
22=22
