2/3y + 8 = 1/4y
2/3y + 8 - 1/4y = 1/4y - 1/4y
2/3y + 8 - 1/4y = 0
2/3y + 8 - 1/4y - 8 = 0 - 8
2/3y - 1/4y = - 8
12(2/3y) - 12(1/4y) = 12(- 8)
8y - 3y = - 96
5y = - 96
5y/5 = - 96/5
y = - 19.2
The answer is y = 19.2
Insert the y value into the equation

Check
2/3y + 8 = 1/4y
2/3(- 19.2) = 1/4( - 19.2)
- 38.4/3 + 8 = - 19.2/ 4
-12.8 + 8 = - 4.8
- 4.8 = - 4.8

2/3y+8=1/4y subtract 8+1/4 y from each side
(2/3-1/4)y=-8
(8/12-3/12)y=-8
(5/12+y=-8 multiply by 12
5y=-96 divide by 5
y=-19.2

2/3y+8=1/4y
multiply the second parts by 12 to remove the divide sign
8y+96=3y
8y-3y= -96
5y= -96
y= -96/5
y= -19.2

(1/4-2/3)y = 8
(-5/12)y=8
y = - 96/5

(2/3y) - (1/4y) = -8
(8/12y) - (3/12y) = -8
5/12y = -8
5 = -8 * (12y)
5 = -96y
Therefore y = (5 / -96)

2/3*y+8=1/4*y
2/3y-1/4*y=-8
5/12*y=-8
y=-96/5
=-19.2
