Solve the equation 12x + 6y = 24 for x

12x + 6y = 24

add -6 to both side

12x + 6y + -6y = 24 + -6y

Combine like terms:

6y + -6y = 0

12x + 0 = 24 + -6y

12x = 24 + -6y

Divide each side by '12'

x = 2 + -0.5y (your answer)

answer: it is 1: 47 pm

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
