72
72
subtract 19 from 91. this will give you 8X equals 72. then you divide 72 by 8, and therefore X will equal to 9
8x = 72
8x=72
The GCF is 9. The LCM is 3528.
Since all of the coefficients are even, it is possible to factor out a 2.
8/x=9/1Cross multiply9x=8x=8/9
80
The answer is No Solution, Assuming the problem is [ x2 = 8x - 90 ]: x2 = 8x - 90 [ or, 2x = 8x - 90 ] 10x = (-90) x = (-9) So, lets plug in "x". 2(-9) = 8(-9) - 90 (-18) = (-72) - 90 (-18) = (-162) And thus, there is no solution.
If this means "what is x when 8x = 9x?" then there is no answer in this Universe. If you want common multiples of 8 & 9 then 72 and all its multiples. (8 & 9 are examples of xy and yx.)
25 percent of 8x = 2x25% of 8x= 25% * 8x= 0.25 * 8x= 2x
