Does anyone know if this is correct?

A person cuts a rope into two pieces that are equal in length. The first piece is 4 times the length of the person’s forearm minus 1 inch. The second piece is 3 times the length of the person’s forearm plus 15 inches.

Construct the linear equation that represents the situation in the given using x as the variable for the person’s forearm.

I came up with 4(X)-1=Y and 3(X)+15=Y
Does anyone know if the equations I came up with correct?
 
Re: linear equation

WHY set them equal to Y?
4X - 1 = 3X + 15
Now solve for X and you're finished.
