Two thirds plus a number plus 4 is 7
Answer:
The answer is \(\frac{7}{3}\)
Step-by-step explanation:
In order to determine the answer, we have to express the statement to a algebraic expression.
The "two thirds" means \(\frac{2}{3}\).
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:
\(\frac{2}{3}+x+4=7\)
Then, we have to solve for "x". We free this variable in any side of the equation:
\(x=-\frac{2}{3}+7-4\\x=\frac{-2+9}{3}\\x=\frac{7}{3}\\\)
Finally, the "x" value is \(\frac{7}{3}\)
