Four less than the difference between a number and seven is seven Use the Algebraic equation and solve for the x
(Use x for the variable )
* I really need help I don’t understand it

x=8

Step-by-step explanation:

Four less than the difference between a number and seven is seven

let's go by parts

Four less

that means if we have a number we subtract 4

so we can write

the difference between a number and seven   remember this is

let's say x is "a number"

so we can rewrite it as

the difference between x and seven

and that means

so we have

put all together and we have

and the final part

is seven

this means that the equation upward is equal to seven

=7

so we have our equation

so there it is our number is 8

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)
