1) 23(x-12) = 552
Решить уравнения:
x-12 = 552/23
x-12 = 24
x = 24+12
x = 36
2) 7(123-4x) = 749
123-4x = 749/7
123-4x = 107
4x = 123-107
4x = 16
x = 16/4
x = 4
Найти корень:
1) x+21x = 1144
22x = 1144
x = 1144/22
x = 52
2) 19x-x-14 = 256
18x = 256+14
18x = 270
x = 270/18
x = 15
3) 6y+11y+15 = 321
17y = 321-15
17y = 306
y = 306/17
y = 18
4) 17x-8x-52 = 2711
9x = 2711+52
9x = 2763
x = 2763/19
x = 307
