Let's begin by first substituting the values into our original equation.
Therefore, 343 R 7 Q 9 S 4 T 8 becomes 343 / 7 - 9 * 4 + 8
To solve this problem, let's follow the BODMAS rule, which guides the order operations should be performed in an equation:
B stands for Brackets
O stands for Orders (i.e. Powers and Square Roots, etc.)
DM stands for Division and Multiplication (left-to-right)
AS stands for Addition and Subtraction (left-to-right)
Using the BODMAS rule, we will start with the division, proceeding from left to right:
1. 343 divided by 7 equals 49.
So, now our equation becomes 49 - 9 * 4 + 8
Next, taking into consideration the BODMAS rule, we'll perform multiplication:
2. 9 times 4 equals 36.
After substituting the values, our equation now reads 49 - 36 + 8
Again, going from left to right we perform subtraction:
3. 49 minus 36 equals 13.
So we get the equation, 13 + 8
As a last step, let's perform addition operation:
4. 13 plus 8 equals 21.
So, the solution of the equation 343 R 7 Q 9 S 4 T 8 is 21.
So, by carefully evaluating the equation, we get the final answer, which is not listed in the given options. Therefore, the correct answer to the equation is 21.
