Решите уравнения за ранее огромное -7*(0,3х - 8) +3 (0,4+5)=8 43,2( 11\18х - 7\8) - 25,5( 9\17х - 2\3)= -59,5

-7*(0,3х - 8) +3 (0,4+5)=8
-2,1x + 56 + 1,2 + 15 = 8
-2,1x = 8 - 56 - 1,2 - 15
-2,1x = -64,2
 2,1x=64,2
 x = 30,57

43,2( 11\18х - 7\8) - 25,5( 9\17х - 2\3)= -59,5
43 1/5 (11/18x - 7/8) - 25 1/2 (9/17x - 2/3) = -59 1/2
216/5(11/18x - 7/8) - 51/2(9/17x - 2/3) = - 119/2

216/5*11/18x - 216/5*7/8  - 51/2*9/17x + 51/2*2/3=-119/2
132/5x - 189/5 - 27/2x + 17 = -119/2
132/5x - 27/2x = -119/2 + 189/5 - 17
164/10x - 135/10x = - 595/10 + 378/10 - 170/10
29/10x = - 387/10
x= - 387/10:29/10 = -387/10*10/29=-387/29 = -13 10/29
