how do you solve this problem 9-2+5x4X
To solve the expression 9-2+5x4X, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).
Let's break it down step by step:
Step 1: Parentheses (if any)
Since there are no parentheses in the expression, we move to the next step.
Step 2: Exponents (if any)
Again, there are no exponents in the expression, so we move on.
Step 3: Multiplication and Division (from left to right)
In the expression, we have 5 multiplied by 4. Multiplying these two numbers gives us 20.
Now we rewrite the expression with the multiplication portion substituted: 9 - 2 + 20X
Step 4: Addition and Subtraction (from left to right)
Now we perform subtraction and addition in the given order.
9 - 2 equals 7.
Now we rewrite the expression: 7 + 20X
Finally, our simplified expression is 7 + 20X. If you have any more information about the variable X, such as its value, you can substitute it in now to find the final numerical solution.
