8(a + 1) - 7a = 98a + 8 - 7a = 9a + 8 = 9a = 9 - 8a = 1
(18y - 12) / 6 + 5y = 143y - 2 + 5y = 148y - 2 = 148y = 16y = 2
5(8e - 1) - 28e = 1940e - 5 - 28e = 1912e - 5 = 1912e = 24e = 2
Therefore, the solutions are:
8(a + 1) - 7a = 9
8a + 8 - 7a = 9
a + 8 = 9
a = 9 - 8
a = 1
(18y - 12) / 6 + 5y = 14
3y - 2 + 5y = 14
8y - 2 = 14
8y = 16
y = 2
5(8e - 1) - 28e = 19
40e - 5 - 28e = 19
12e - 5 = 19
12e = 24
e = 2
Therefore, the solutions are:
a = 1y = 2e = 2
