To solve for X in this equation, you would subtract both sides by 14 because our goal is to get X on its own. If we write it out, we see that
X + 14 - 14 = 56 - 14
X=42
Because we have a positive 14, a negative 14 will average out to be 0, but what you do to one side, you must do to the other.

Answer:
-5.7
Step-by-step explanation:
OUR EQUATION IS A QUADRATIC EQUATION
Let Δ be our dicriminant :
- a= 1
- b= 5
- c= -4
- Δ= 5²-4*1*(-4) =25 +16 =41≥0
- so we have two solutions x and y
- x= (-5-√41)/2 = -5.7
