Нужно решения уравнений.Спасибо
1) x + 38 = 113 4) (у - 3)*(4 - y) = 0 7) 4k - 1 = 27
x = 113 - 38 (у - 3) = 0 или (4 - y) = 0 4k = 27 + 1
x = 75 y = 3 или -y = -4 4k = 28
2) 5a + 2a = 35 y = 3 или y = 4 k = 7
7a = 35 5) p + (27 - 19) = 34 8) 33c = 64 + c
a = 5 p + 8 = 34 33c - c = 64
3) b*b + 9 = 34 p = 34 - 8 32c = 64
b*b = 34 - 9 p = 26 c = 2
b*b = 25 6) n : 8 = n : 6 - 2 9) 7e + 28 = 84
b^2 = 25 n : 8 = (n - 12) : 6 7e = 84 - 28
b = √25 n * 6 = 8 * (n - 12) 7e = 56
b = 5 6n = 8n - 96 e = 8
6n - 8n = - 96
-2n = -96
n = -96 : -2
n = 48
