Question

15 38:(2 34x+5 56)-1 12=34

Answer 1

15 38:(2 34x+5 56)-1 12=34
1238:(114x+5 56)=34+1 12
1238:(114x+5 56)=34+1 24
1238:(114x+5 56)=1 5/4
1238:(114x+5 56)=9/4
114x+5 56=1238:9/4
114x+5 56=1238*4/9
114x+5 56=1232*1/9
114x+356=123/18
11/4х=123/18-35/6
11/4х=123/18-105/18
11/4х=18/18
11/4х=1
х=1:11/4=1*4/11=4/11
