localid="1648828247026" $x + \frac{y}{3}$

Short Answer

Expert verified

The value of the expression is10.

Step by step solution

Step-1 – Order of operations

To evaluate any expression involving more than one operation, follow the below order of operations:

First evaluate expressions inside grouping symbols like parentheses ( ) or brackets [ ].
Evaluate the exponents.
Perform Multiplication and division from left to right.
Perform addition and subtraction from left to right.

Step-2 – Divide from left to right

To evaluate the expression $x + \frac{y}{3}$ , substitute 6 for x and 12 for y in the given expression and simplify further as shown below

$\begin{matrix} x + \frac{y}{3} = 6 + \frac{12}{3} \\ = 6 + 4 \end{matrix}$

Step-3 – Add the numbers

Now to simplify further, add the numbers to get

$\begin{matrix} x + \frac{y}{3} = 6 + 4 \\ = 10 \end{matrix}$

Thus, the value of the expression is 10.
