4.5x+7/9x+2 1/3+1/6x=5 1/18 ! 20 points!

X = 369/560

You would combine like terms , then dived across the equal sign to get x by it’s self.

5 1/18 = 4.5x + 7/9x + 2 1/3 + 1/6x

make sure they have the same denominator

5 1/18 = 4.5x + 14/18x + 2 6/18 + 3/18x

subtract 2 6/18 from both sides

5 1/18 - 2 6/18 = 4.5x + 14/18x + 2 6/18 - 2 6/18 + 3/18x

4 19/18 - 2 6/18 = 4.5x + 14/18x + 2 6/18 - 2 6/18 + 3/18x

2 13/18 = 4.5x + 14/18x + 3/18x

convert 4.5x to fraction form with same denominator

2 13/18 = 9/18x + 14/18x + 3/18x

combine like terms

2 13/18 = 9/18x + 14/18x + 3/18x

2 13/18 = 26/18x

simplify

2 13/18 = 1 8/18x

your answer is: x = 1  23/26

(if this helps, please give brainliest as well; hope it does!)

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

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.
