Answer:

y = -0.7

Explanation:

Reorder the terms:

-2.7 + y = -2.0 + 2y

Solving

-2.7 + y = -2.0 + 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.

-2.7 + y + -2y = -2.0 + 2y + -2y

Combine like terms: y + -2y = -1y

-2.7 + -1y = -2.0 + 2y + -2y

Combine like terms: 2y + -2y = 0

-2.7 + -1y = -2.0 + 0

-2.7 + -1y = -2.0

Add '2.7' to each side of the equation.

-2.7 + 2.7 + -1y = -2.0 + 2.7

Combine like terms: -2.7 + 2.7 = 0.0

0.0 + -1y = -2.0 + 2.7

-1y = -2.0 + 2.7

Combine like terms: -2.0 + 2.7 = 0.7

-1y = 0.7

Divide each side by '-1'.

y = -0.7

Simplifying

y = -0.7
