Answer: x = -7y

Explanation:

Steps for Solving Linear Equation

3x+14y=x

Subtract x from both sides.

3x+14y−x=0

Combine 3x and −x to get 2x.

2x+14y=0

Subtract 14y from both sides. Anything subtracted from zero gives its negation.

2x=−14y

Divide both sides by 2.

2x/2=-14y/2

Dividing by 2 undoes the multiplication by 2.

x=-14y/2

​Divide −14y by 2.

x=−7y
