step one 3y - 51 = -5y plus 115
step two 8y = 166
step three y = 20.75

3(y - 17) = - 5(y - 23)
3y - 51 = - 5y + 115
3y + 5y = 115 + 51
8y = 166
y = 166 / 8
y = 20 3/4
Proof:
3(20 3/4 - 17) = - 5(20 3/4 - 23)
62 1/4 - 51 = - 103 3/4 + 115
11 1/4 = 11 1/4

I think u can solve like this:
3(y-17)=-5(y-23)
3y-51 =-5y+115
3y-51 =-5y+115
3y+5y =115+51
8y =166
y =166/8
y =20.75
Is it help?

3(y - 17) = -5(y - 23)
now distribute
3y - 51 = -5y +115
add 5y to both sides
8y - 51 = 115
add 51 to both sides
8y = 166
divide both sides by 8
y = 166/8 = 20.75

you can solve this several ways...but I'll use a standard algebraic technique
3(y-17) = -5(y-23)
3y-51 = -5y+115
8y = 166
y = 166/8 = 83/4 = 20.75 or whatever form you like.

3(y-17) = -5(y-23)
-> 3y - 51 = -5y + 115
-> 3y + 5y = 51 + 115
-> 8y = 166
-> 8y/8 = 166/8
-> y = 20.75
i'm still here if you have further questions :)

3(y-17) = -5(y-23)
3y-51=-5y+115
3y=-5y+166
8y=166
y=20 3/4

3(y-17) = -5(y-23)
multiply out 3 and -5
3y - 51 = -5y + 115
combine like terms
8y = 166
divide by 8
y = 20.75

y= -8
3(y-17) = -5(y-23)
3y-51 = -5y +115
(add 5y to both sides)
8y-51 = 115
(add 51 to both sides)
8y = 166
(divide both side by 8 to get y by itself)
y = 20.75

3y - 51 = - 5y + 115
8 y = 166
y = 166 / 8
y = 83 / 4
