Question

решите уравнения 14x-4x-48=240,25b-7b-9=279,16a-7a+96=222,20y+5y+y+19=227 PLEAS РЕШИТЕ

Answer 1

1) 14x - 4x - 48 = 240
14x - 4x = 240+48
10x = 288
x = 28.8
2) 25b - 7b - 9 = 279
25b - 7b = 279 + 9
18b = 288
b = 16
3) 16a - 7a + 96 = 222
16a - 7a = 222 - 96
9a = 126
a =14
4) 20y + 5y + y + 19 = 227
20y + 5y + y = 227 - 19
26y = 208
y = 8
