Answer 1

A) (x-152)*59 = 6018 |:59
x-152 = 102
x = 102+152
x = 254
б) 975*(y-361) = 14625 |:975
y-361 = 15
y = 15+361
y = 376
в) (30142+z):876 = 49 |*876
30142+z = 42924
z = 42924-30142
z = 12782
г) 51815:(p-975) = 1205 |*(p-975)
51815 = 1205*(p-975) |:1205
43 = p-975
p-975 = 43
p = 43+975
p = 1018
д) 13x+15x-24 = 60
28x = 60+24
28x = 84 |:28
x = 3
е) 18y-7y-10 = 12
11y = 12+10
11y = 22 |:11
y = 2
