5(x+ 1)- 100(x+3)-3 = 0

5x+5- 100x-300-3=0

-95x-298=0

x=-298/95

2. There is something wrong with (3y+122)/4-(y+2)/5.

3 、( y- 1)/(y-2)=2-(y+2)/5

The left and right sides are the same as × 5 (y-2): y-1=10 (y-2)-y? +4

Finishing: y? -9y+ 15=0 just solve this equation.

4 、( 1-x)/(x-3)=(x+2)/6- 1

Left and right x 6 (x-3): 6 (1-x) = x? -x+6-6x+ 18

Finishing: x? -x+ 18=0 just solve this equation.

5、2/(y-6) - 18y=(y+2)/9

The left and right sides are the same as × 9 (y-6): 2-18y (y-6) × 9-(y+2) (y-6) = 0.

Finishing: 16 1y? +4y-962=0 to solve this equation.
