im having trouble with this one too.
6y-8=-6+3y+13
heres what ive done so far...not good.
6y-8=-6+3y+13
6y-8=7+3y
-6y -6y
8=7-3y
Ok I think this is how it goes:
6y-8=-6+3y+13
First add 8 to both sides
6y=15+3y
Next subtract your 3y from both sides
3y=15
so y must = 5
3(5)= 15
I think this is right
do you combine like terms before you add the 8 to both sides?
The order of operations will not affect the answer, but it is best to "clean up" the equation first by combining terms, so the next step to perform will be easier to figure out.
To solve the equation 6y-8=-6+3y+13, you need to isolate the variable y. Here's how to do it step by step:
1. Start by simplifying both sides of the equation. Combine like terms on each side.
6y - 8 = -6 + 3y + 13
On the right side, combine -6 and 13:
6y - 8 = 7 + 3y
2. Now, to isolate y, you want to move all terms containing y to one side of the equation. To do this, subtract 3y from both sides of the equation:
6y - 8 - 3y = 7 + 3y - 3y
Simplify:
3y - 8 = 7
3. Next, you want to move the constant term (-8) to the other side of the equation. To do this, add 8 to both sides:
3y - 8 + 8 = 7 + 8
Simplify:
3y = 15
4. Finally, divide both sides of the equation by 3 to solve for y:
(3y) / 3 = 15 / 3
Simplify:
y = 5
So, the solution to the equation is y = 5.
