Answer: 0.2
Explanation:
Simplifying
3y + -1 = 8y + -2
Reorder the terms:
-1 + 3y = 8y + -2
Reorder the terms:
-1 + 3y = -2 + 8y
Solving
-1 + 3y = -2 + 8y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-8y' to each side of the equation.
-1 + 3y + -8y = -2 + 8y + -8y
Combine like terms: 3y + -8y = -5y
-1 + -5y = -2 + 8y + -8y
Combine like terms: 8y + -8y = 0
-1 + -5y = -2 + 0
-1 + -5y = -2
Add '1' to each side of the equation.
-1 + 1 + -5y = -2 + 1
Combine like terms: -1 + 1 = 0
0 + -5y = -2 + 1
-5y = -2 + 1
Combine like terms: -2 + 1 = -1
-5y = -1
Divide each side by '-5'.
y = 0.2
