R+-3.5=5.3 solve for r

8.8=r

Step-by-step explanation:

You can solve the equation backwards and do 5.3+3.5=8.8

To check 8.8-3.5=5.3 (OR 8.8 + (-3.5) = 5.3

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)
