Solve for y.
1. y= -1/4
2. 1/4.
3. y=41/4.
4.41/25
what is the correct answer?

1. y= -1/4

Step-by-step explanation:

y/5 + 3/10 = (y+2)/7

Get a common denominator for the left hand side

2y/10 + 3/10 = (y+2)/7

(2y+3)/10 = (y+2)/7

Using cross products

(2y+3) *7 = 10*(y+2)

Distribute

14y+21 = 10y+20

Subtract 10y from each side

14y-10y +21 = 10y-10y+20

4y+21 =20

Subtract 21 from each side

4y+21-21 = 20-21

4y = -1

Divide by 4

4y/4 = -1/4

y = -1/4
