Question

решите уравнение 
(x+36.1)*5.1=245.82       (m-0.67)*0.02=0.0152

(x+24.3)/18.3=3.1              (y-15.7)/19.2=407

Answer 1

1) (x + 36.1) * 5.1 = 245.82
     x + 36.1 = 245.82 : 5.1
     x + 36.1 = 48.2
     x = 48.2 - 36.1
     x = 12.1
2) (m - 0.67) * 0.02 = 0.0152
     m - 0.67 = 0.0152 : 0.02
     m - 0.67 = 0.76
     m = 0.76 + 0.67
     m = 1.43
3) (x + 24.3) : 18.3 = 3.1
     x + 24.3 = 3.1 * 18.3
     x + 24.3 = 56.73
     x = 56.73 - 24.3
     x = 32.43
4) (y - 15.7) : 19.2 = 407
     y - 15.7 = 407 * 19.2
     y - 15.7 = 7814.4
     y = 7814.4 + 15.7
     y = 7830.1
