Answer:
x=1
Step-by-step explanation:
Let's solve your equation step-by-step.
10−5x+1=7x+11−12
Step 1: Simplify both sides of the equation.
10−5x+1=7x+11−12
10+−5x+1=7x+11+−12
(−5x)+(10+1)=(7x)+(11+−12)(Combine Like Terms)
−5x+11=7x+−1
−5x+11=7x−1
Step 2: Subtract 7x from both sides.
−5x+11−7x=7x−1−7x
−12x+11=−1
Step 3: Subtract 11 from both sides.
−12x+11−11=−1−11
−12x=−12
Step 4: Divide both sides by -12.
−12x
−12
=
−12
−12
x=1

Answer:
x = (-3±√5)/2
Step-by-step explanation:
Matching the given equation to the pattern ...
... ax² +bx +c = 0
we see that a=1, b=3, c=1.
The solution to the above pattern is given by the quadratic formula ...
... x = (-b±√(b²-4ac))/(2a)
Substituting the values of a, b, c that we found, the formula gives ...
... x = (-3±√(3²-4·1·1))/(2·1)
... x = (-3±√5)/2
The answer is C because x2 is a parabola
