What is 5x-8➗3=11x-9➗5

Set this up as a proportion.  As proportions you can make the equation:

(5x-8)(5) =(11x-9)(3).

From here, simply distribute and simplify.

(5)(5x) + (5)(-8) = (11x)(3) + (-9)(3)

(25x) + (-40) = (33x) + (-27)

25x - 40 = 33x - 27

Now solve for x.

25x (-25x) -40 = 33x (-25x) -27

-40 = 8x - 27

-40 (+27) = 8x -27 (+27)

-13 = 8x

-13/8 = 8x / 8

-1 5/8 = x

x = -1 5/8

10x

step-by-step explanation:

the greatest common factor 30 and 20 is 10

5 is a common factor of 30 and 20 but 10 is also a factor and 10 is greater than 5 so 5 will definitely not be apart of our answer

now the most amount of x's you factor our is just 1 factor of 1

so 10x the gcf of the terms in the polynomial

maybe - definition of supplementary angles. im not sure. sorry
