Simplifying
8y + -6 = 5y + 12
Reorder the terms:
-6 + 8y = 5y + 12
Reorder the terms:
-6 + 8y = 12 + 5y
Solving
-6 + 8y = 12 + 5y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-5y' to each side of the equation.
-6 + 8y + -5y = 12 + 5y + -5y
Combine like terms: 8y + -5y = 3y
-6 + 3y = 12 + 5y + -5y
Combine like terms: 5y + -5y = 0
-6 + 3y = 12 + 0
-6 + 3y = 12
Add '6' to each side of the equation.
-6 + 6 + 3y = 12 + 6
Combine like terms: -6 + 6 = 0
0 + 3y = 12 + 6
3y = 12 + 6
Combine like terms: 12 + 6 = 18
3y = 18
Divide each side by '3'.
y = 6
Simplifying
y = 6

sry, might be kind of confusing, kinda hard to write all of the steps on the computer! lol
hope this helps!
Today,I took a test over stuff like this in algebra....
Some of it can be hard!
