Can i have with this problem plz(x-1)1/3=2 ?

Solving for x gives x=7

Step-by-step explanation:

First lets rewrite our equation clear, which from the question reads as :

    Eqn(1).

This is a case of an equation with one variable (i.e. one uknown) denoted as .

The question is asking as to solve this equation and obtain the value of .

To do so we start by rewriting and simplifying the equation as follow:

which is the same as

Here we have a fraction on the left hand side reading as and an integer on the right hand side as . Thus we move the denominator of the fraction, in this case to the right hand side where we multiply it with , to eliminate our fraction and solve for  as follow:

(Note how we transferd from the left hand side to the right hand side, the sign changed from negative to positive).

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
