Respuesta :

9/2 is the answer


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

Answer:

The answer is [tex]\frac{7}{3}[/tex]

Step-by-step explanation:

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

The "two thirds" means [tex]\frac{2}{3}[/tex].

Then "plus a number" means [tex]+x[/tex]. "x" is the variable that we want to know its value.

Then "plus 4" means +4.

So, the algebraic expression is:

[tex]\frac{2}{3}+x+4=7[/tex]

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

[tex]x=-\frac{2}{3}+7-4\\x=\frac{-2+9}{3}\\x=\frac{7}{3}\\[/tex]

Finally, the "x" value is [tex]\frac{7}{3}[/tex]
