What two thirds in equal to negative eight times the number?
Let the required number be equal to x According to the given equation 2/3 of x= 8(-x) 2x/3= -8x 2x/3+(-8x)=0 2x/3-8x=0 2x/3-24x/3=0 -21x/3=0 -21x=0 x=0/-21 x=0 Hence the number would be 0.

What is the solution to X2equals8x-90?
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.
