I believe the answer would be
x = \frac{ - 5 + \sqrt{505} }{12} and \: \frac{ - 5 - \sqrt[]{505} }{12}
Good Luckkk.:-)

Step 1 move all terms to one side
example: 6x^2+5x-20=0
step 2 use the quadratic formula.
How: In general ax^2+c=0, there exists two solutions.

Next: In this case a=6 , b=5, c= -20

Last step: which is Simplify leaves you with the top answer!

What is 3a+2c=26 solve for a and c
blondinia [14]

Simplifying

3a + 2b + c = 26

Solving

3a + 2b + c = 26

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-2b' to each side of the equation.

3a + 2b + -2b + c = 26 + -2b

Combine like terms: 2b + -2b = 0

3a + 0 + c = 26 + -2b

3a + c = 26 + -2b

Add '-1c' to each side of the equation.

3a + c + -1c = 26 + -2b + -1c

Combine like terms: c + -1c = 0

3a + 0 = 26 + -2b + -1c

3a = 26 + -2b + -1c

Divide each side by '3'.

a = 8.666666667 + -0.6666666667b + -0.3333333333c

Simplifying

a = 8.666666667 + -0.6666666667b + -0.3333333333c
