Question

помогите пж номер 560

Answer 1

7(x-19) = 133
X-19 = 133/7
X-19 = 19
X = 19 + 19
X = 38

9(213-2x) = 927
213-2x = 927/9
213-2x = 103
213-103 = 2x
110 = 2x
X = 110/2
X = 55

1344/(x+20) = 32
X + 20 = 1344/32
X + 20 = 42
X = 22

384/(51-5x) = 24
51-5x = 384/24
51-5x = 16
51-16 = 5x
35 = 5x
X = 35/5
X = 7
