-8-5y = 12-9y 9y-5y - 12+8 4y = 20 y = 5
5y+8=7y subtract 5y from each side , 5y+8=7y -5y -5y 8=2y /2 /2 4=y
5y-8 = 16 5y = 16+8 5y = 24 y = 24/5 = 4.8
8 - 5y = 12 -5y = 4 y = -4/5
If: 3y+8 = 5y-20 Then: 3y-5y = -20-8 So: -2y = -28 And: y = -28/-2 => y = 14
8 + y = 7 + 5y <----they are equal to the same number so are equal to each other 4y = 1 y = 0.25
-8-5y = 12-9y 9y-5y - 12+8 4y = 20 y = 5
8+y = 7+5y y-5y = 7-8 -4y = -1 y = 1/4
5y+8=7y subtract 5y from each side , 5y+8=7y -5y -5y 8=2y /2 /2 4=y
8 + 5y = 18 Therefore, 5y = 10 y = 10/5 y = 2
5y+8=7y 2y=8 y=4
5y-8 = 16 5y = 16+8 5y = 24 y = 24/5 = 4.8
8 - 5y = 12 -5y = 4 y = -4/5
If: 3y+8 = 5y-20 Then: 3y-5y = -20-8 So: -2y = -28 And: y = -28/-2 => y = 14
Well, honey, 5y is equal to 5 times y. It's as simple as that. So if someone tells you 5y, just remember they're talking about 5 times whatever the heck y represents. Now go on and show off your math skills!
3y-8+5y = 2y-39 3y+5y-2y = -39+8 6y = -31 y = -31/6
4x + 5y = -8 is an equation with two variables. While you can solve for y = something, you won't come up with a single number. For example, 4x + 5y = -8 5y = -4x - 8 y = -4x/5 - 8/5. And you can do the same for x = something in terms of y.
