Answer:
I think its -12. If you apply y2-y1/ x2-x1 to the equation.
The value of x is 1.25 or 1 1/4
Explanation
==============================
275x=500-125x
Move variable to the left side and change its sign
275x+125x=500
Collect the like terms
275x+125x=500 =====> 400x=500
Divide both sides of the equation by 400
400x/400=500 =======> x=5/4 which is the same as 1 1/4 or 1.25
