Your answer should be: 1
Step-by-step explanation:
1: Solve one Equation for one of the variables
2: Substitute (plug-in) this expression into the other equation and solve
3: Resubtitue the value into the original equation to find the corresponding variable
Answer:
Option B.
Step-by-step explanation:
The given equation is
Subtract both sides by 17.
.... (1)
If a quadratic equation is , then by quadratic formula
In equation (1), a=1, b=2 and c=-16. Using quadratic formula we get
Taking out common factors.
Therefore, the correct option is B.
