1) 3x + 5 = 143x = 14 - 53x = 9x = 3
2) 2y - 3 = 72y = 7 + 32y = 10y = 5
3) 4a + 8 = 204a = 20 - 84a = 12a = 3
4) 5b - 2 = 135b = 13 + 25b = 15b = 3
5) 6c + 10 = 286c = 28 - 106c = 18c = 3
Таким образом, решения примеров:1) x = 32) y = 53) a = 34) b = 35) c = 3
1) 3x + 5 = 14
3x = 14 - 5
3x = 9
x = 3
2) 2y - 3 = 7
2y = 7 + 3
2y = 10
y = 5
3) 4a + 8 = 20
4a = 20 - 8
4a = 12
a = 3
4) 5b - 2 = 13
5b = 13 + 2
5b = 15
b = 3
5) 6c + 10 = 28
6c = 28 - 10
6c = 18
c = 3
Таким образом, решения примеров:
1) x = 3
2) y = 5
3) a = 3
4) b = 3
5) c = 3
