Question

Two thirds plus a number plus 4 is 7

Answer 1

9/2 is the answer


7-4= 3
3times 3/2 is 9/2

Answer 2

The answer is
`(7)/(3)`

Explanation:

In order to determine the answer, we have to express the statement to a algebraic expression.

The "two thirds" means
`(2)/(3)`.

Then "plus a number" means
`+x`. "x" is the variable that we want to know its value.

Then "plus 4" means +4.

So, the algebraic expression is:

`(2)/(3)+x+4=7`

Then, we have to solve for "x". We free this variable in any side of the equation:

`x=-(2)/(3)+7-4\\x=(-2+9)/(3)\\x=(7)/(3)\\`

Finally, the "x" value is
`(7)/(3)`
