Most Upvoted Answer
Find the value if x=3, a=(-1), b=(-2)The question is :2-6x+4a+3b?
Step 1: Substitute the Values
To find the value of the expression 2 - 6x + 4a + 3b, we first substitute the given values:
- x = 3
- a = -1
- b = -2
Step 2: Plugging in Values
Now we replace x, a, and b in the expression:
- 2 - 6(3) + 4(-1) + 3(-2)
Step 3: Perform Calculations
- Calculate 6(3):
- 6 * 3 = 18
- Calculate 4(-1):
- 4 * -1 = -4
- Calculate 3(-2):
- 3 * -2 = -6
Now, substituting these results back into the expression:
- 2 - 18 - 4 - 6
Step 4: Simplifying the Expression
Now we perform the operations step by step:
- Start with 2 - 18:
- 2 - 18 = -16
- Next, subtract 4:
- -16 - 4 = -20
- Finally, subtract 6:
- -20 - 6 = -26
Final Result
The final value of the expression when x = 3, a = -1, and b = -2 is:
- -26
This process combines substitution and arithmetic operations to evaluate the expression accurately.
