Answer:

5x - 2y = x + 14 Given

5x = x + 14 + 2y Addition property

4x - 14 = 2y Subtraction property

2x - 7 = y Division property

y = 2x - 7 Symmetric property

Step-by-step explanation:

The give expression is

5x - 2y = x + 14

To solve for y, let's use the addition and subtraction propertu of equality as follows

5x - 2y + 2y = x + 14 + 2y

5x = x + 14 + 2y

5x - x - 14 = x + 14 + 2y - x - 14

4x - 14 = 2y

Then, dividing both sides by 2 (division property), we get

4x/2 - 14/2 = 2y/2

2x - 7 = y

Therefore, y = 2x - 7 by the symmetric property.

So, the answer is:

Statement Reason

5x - 2y = x + 14 Given

5x = x + 14 + 2y Addition property

4x - 14 = 2y Subtraction property

2x - 7 = y Division property

y = 2x - 7 Symmetric property
