Question

Solve for x if the equation is 2/5(x+1)=g,

Answer 1

`(2)/(5)(x+1)=g\ \ \ |multiply\ both\ sides\ by\ (5)/(2)\\\\x+1=(5)/(2)g\ \ \ |subtract\ 1\ from\ both\ sides\\\\\boxed{x=(5)/(2)g-1}\to\boxed{x=(5g-2)/(2)}`

Answer 2

In order to get x, one needs to simply rearrange the whole equation to solve for x.

`(2)/(5)(x+1)=g`

Multiply the two sides of the equation by 5/2.

`(5)/(2) [(2)/(5) (x+1)=g]`

Distributing the 5/2 and simplifying, the resulting equation would be:

`(10)/(10) (x +1)= (5)/(2)g`

`(x +1)= (5)/(2)g`


Simplifying the equation and subtracting 1 from each side of the equation the final equation for solving x is:

`x = (5)/(2) g - 1`
