Question

解方程 3x+5/2=2x-1/3 x-3/-5=3x+4/15 3y-1/4-1=5y-7/6 5y+4/3+y-1/

Answer 1

3x+5/2=2x-1/3

x=-1/3-5/2

x=-17/6

x-3/-5=3x+4/15

2x=3/5-4/15

2x=2/15

x=1/15

3y-1/4-1=5y-7/6

3y-5y=-7/6+1+1/4

2y=7/6-5/4

2y==2/24

y=-1/24

5y+4/3+y-1/4=2-5y-5/12

6y+5y=2-5/12-4/3

11y=1/12

y=1/132

3x-1/7-3-x/2=1

3x-x/2=29/7

5x=58/7

x=58/35
