Answer:

y = 4

Explanation:

Simplifying

2[4y + -9] = 14

Reorder the terms:

2[-9 + 4y] = 14

[-9 * 2 + 4y * 2] = 14

[-18 + 8y] = 14

Solving

-18 + 8y = 14

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '18' to each side of the equation.

-18 + 18 + 8y = 14 + 18

Combine like terms: -18 + 18 = 0

0 + 8y = 14 + 18

8y = 14 + 18

Combine like terms: 14 + 18 = 32

8y = 32

Divide each side by '8'.

y = 4
