Answer:
y = 6.4
Explanation:
Simplifying
1.1 = 13.9 + -2y
Solving
1.1 = 13.9 + -2y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '2y' to each side of the equation.
1.1 + 2y = 13.9 + -2y + 2y
Combine like terms: -2y + 2y = 0
1.1 + 2y = 13.9 + 0
1.1 + 2y = 13.9
Add '-1.1' to each side of the equation.
1.1 + -1.1 + 2y = 13.9 + -1.1
Combine like terms: 1.1 + -1.1 = 0.0
0.0 + 2y = 13.9 + -1.1
2y = 13.9 + -1.1
Combine like terms: 13.9 + -1.1 = 12.8
2y = 12.8
Divide each side by '2'.
y = 6.4
Simplifying
y = 6.4
