4y-10y+y+34 = 5y+30-2y
-6y+y+34 = 5y+30-2y
-5y+34 = 5y+30-2y
-5y+34 = 3y+30
-5y = 3y-4
-8y = -4
y = -4 / -8
y = 1/2

We have an equation with many steps.

Steps:

1-Simplify the sides of the equation separately.

2-Separate the variables terms from the constants.

3-Eliminate the coefficient using division.

We have this:

4y-10y+y+34= 5y+30-2y

Simplify the left or right side first.

I will simplify the left side first.

-5y + 34 = 5y + 30 - 2y

I will now simpllify the right side of the equation.

-5y + 34 = 3y + 30

Now, it's time to separate the variable terms from the constants.

In other words, put all the x terms on one side and all the constants on the other side.

You decide which side of the equation you want to variable terms and constants to fall on.

We have this:

-5y + 34 = 3y + 30

-5y - 3y = -34 + 30

-8y = -4

We now divide both sides of the equation by -8 to eliminate the coefficient. What is our coefficient? The -8 standing next to y. See it?

y = - 4 divided by - 8

y = 1/2

Did you follow?

4y - 10y + y + 34 = 5y + 30 - 2y

Simplify:

-5y + 34 = 5y + 30 - 2y

Rearrange:

-5y + 34 = 5y - 2y + 30

Simplify:

-5y + 34 = 3y + 30

Move y-values to the right side of the equal sign and the constants (numbers) to the left side.

34 - 30 = 3y + 5y

Simplify:

4 = 8y

y = 4/8 = 1/2 = 0.5

This is easy

4y-10y+y+34= 5y+30-2y

=> 4y+y-10y-5y+2y=30-34 (bring what's the same together)
=> 7y-15y= -4 (simplify everything [you can leave this out] )
=> -8y= -4
=> 8y=4 (change the signs)
=> y=4/8m (to get rid of the '8y' bring over and divide)

answer= y=0.5 or 1/2

group the y's together
(4y-10y+y)+34=(5y-2y)+30

Then add or subtract the y's together
-5y+34=3y+30

Bring the y's over to the left by subtracting 3y from both sides
(-5y-3y)+34=(3y-3y)+30

Simplify the y's bring the numbers to the right by subtracting 34 from both sides
-8y+(34-34)=30-34

Simplify the numbers
-8y= -4

get the variable alone by dividing each side by -8
-8y/-8 = -4/-8

simplify
y = 1/2

4y-10y+y+34=5y+30-2y combine like terms
-5y+34=3y+30 subtract 3y from both sides
-8y+34=30 subtract 34from both sides
-8y=-4 divide both sides by 2
y=1/2

Well, first try to group like-terms together.

4y - 10y + y + 34 = 5y + 30 - 2y

4y - 10y +y = 7y. 5y - 2y = 3y.

So 7y + 34 = 3y + 30.

From there, all you have to do is put all of the "y"s to one side, and the numbers without "y"s to the other side.

I hope this helps!

4y-10y+y = -5y

5y-2y = 3y

-5y + 34 = -3y + 30
-2y = -4
y = 2

4y-10y+y+34= 5y+30-2y

Move all the y's on to one side (remember to change symbol)

4y-10y+y-5y+2y=30-34

then add all of them together

-12y=-4

then divide -4

y=2

-5y+34 = 3y+30
34 - 34 = 0
30 - 34 = -4=-5y = -4+3y

-5y - 3y = -8y
3y - 3y = 0 =-8y = -4

-8y ÷ -8 = y


-4 ÷ -8 = 1/2

The solution to your equation is:
y = 1/2
