The first equation is 
(Equation 1)
The second equation is 
(Equation 2)
Putting the value of x from equation 1 in equation 2.
we get,
by simplifying the given equation,
Using discriminant formula,
Now the formula for solution 'x' of quadratic equation is given by:
Hence, these are the required solutions.
Answer: 30 degrees
Step-by-step explanation:
1 hour = 60 min = 360 degree
1 min = 360/60 degree
1 min = 6 degree
and the gap of hour hand and minute hand at 1pm, is of 5 min
therefore acute angle formed is 5 X 6 = 30 degrees.

Answer:
12 units
Step-by-step explanation:
base is x
one of the legs measure 4x-6
therefore, perimeter is equal to
2 (4x - 6) + x = 96
8x - 12 + x = 96
9x = 96 + 12
9x = 108
x = 108/9 = 12 units
