Question

Решите уравнение 8 3/4\(2/3х+4)=7/8

Answer 1

2/3х+4=8 3/4÷7/8
2/3х+4=35/4×8/7
2/3х=10-4
2/3х=6
х=6÷2/3=6×3/2=9
8 3/4÷(2/3×9+4)=7/8
35/4÷(6+4)=7/8
35/4×1/10=7/8
7/8=7/8

Answer 2

8*3/4 : (2/3х+4) = 7/8
24/4 : (2/3х+4) = 7/8
6 : (2/3х+4) = 7/8
6/1 * (3х+4)/2=7/8
3*(3х+4)=7/8
9х+12=7/8
9х=7/8-12
9х=-0,875-12
9х=-11,125
х=-11,125/9
х=-1,23
