What will be the result of this algebraic expression:
5x−6
if we place
x=−2
To solve this problem, we will evaluate the algebraic expression 5x−6 by substituting the value of x=−2 into it.
Step-by-step solution:
- Step 1: Substitute x=−2 into the expression 5x−6. This gives:
5(−2)−6
- Step 2: Perform the operations in the expression. Start with the multiplication:
5(−2)=−10
- Step 3: Substitute the result of the multiplication back into the expression:
−10−6
- Step 4: Now perform the subtraction:
−10−6=−16
Therefore, the result of the expression when x=−2 is −16.
Comparing this result with the given choices, we conclude that the correct choice is:
−16
