Question

помогите решить уравнения
3/4*(5/6-2/3x) =5x-4 1/2 ​

Answer 1

Ответ:

3/4*(5/6-2/3x)=5x-4 1/2;

3/4• 5/6 - 2/3х• 3/4= 5х- (2•4+1)/2;

1/4• 5/2 - 1/1х• 1/2= 5х- 9/2;

5/8 - 1/2х + 9/2= 5х;

5/8+ 9/2= 5х +1/2х;

5/8 +(9•4)/(2•4)= 5 1/2х;

5/8+ 36/8= (5•2+1)/2Х;

41/8= 11/2х;

Х= 41/8: 11/2;

Х= 41/8• 2/11;

Х= 41/4• 1/11;

Х=41/44
