Subtract the polynomials:

(6xy+4x−8y)−(3x+2y+7xy−4)

x - 10y - xy + 4

Step-by-step explanation:

(6xy+4x−8y)−(3x+2y+7xy−4)

= 6xy+4x−8y−3x-2y-7xy+4

= 6xy-7xy+4x−3x−8y-2y+4

= x - 10y - xy + 4

because its not ur topic and its not for is for homework not that.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
