8-2y=3y-2<br> Help me please
lesya692 [45]
This seems like a lot more work than it is, but here we go
Simplifying<span>8 + -2y = 3y + -2 
 Reorder the terms: 8 + -2y = -2 + 3y 
 Solving 8 + -2y = -2 + 3y Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right.
  Add '-3y' to each side of the equation. 8 + -2y + -3y = -2 + 3y + -3y Combine like terms: -2y + -3y = -5y 8 + -5y = -2 + 3y + -3y 
 Combine like terms: 3y + -3y = 0 8 + -5y = -2 + 0 8 + -5y = -2 Add '-8' to each side of the equation. 8 + -8 + -5y = -2 + -8 
 Combine like terms: 8 + -8 = 0 0 + -5y = -2 + -8 -5y = -2 + -8 Combine like terms: -2 + -8 = -10 -5y = -10
  Divide each side by '-5'. y = 2 
 Simplifying y = 2</span><span>

What’s a Equlivant fraction for 2/8 3/8 and 4/8<br><br> Need ASAP<br> Thanks
DaniilM [7]

To get the equivalent fractions, you simply have to multiply the fraction with another fraction that would equal to 1.

2/8 x 2/2 (this is equal to 1) = 4/16; 1/4

3/8 x 2/2 = 6/16; 9/24

4/8 x 2/2 = 8/16; 1/2
