Step 1: Understand the Expression
To find the value of the expression 3.2 - 6x + 4a + 3b, we need to substitute the given values of b, a, and x.
- b = -2
- a = -1
- x = 3.2
Step 2: Substitute the Values
Now, let's replace a, b, and x in the expression:
- Original Expression: 3.2 - 6x + 4a + 3b
- Substitute the values: 3.2 - 6(3.2) + 4(-1) + 3(-2)
Step 3: Calculate Each Term
Now, we will calculate each term in the expression:
- Calculate -6x:
-6(3.2) = -19.2
- Calculate 4a:
4(-1) = -4
- Calculate 3b:
3(-2) = -6
Step 4: Combine the Results
Now, we can combine all the calculated terms:
- Expression becomes:
3.2 - 19.2 - 4 - 6
Step 5: Perform the Final Calculation
Now, let's do the final calculation step-by-step:
- Start with 3.2:
3.2 - 19.2 = -16
- Now subtract 4:
-16 - 4 = -20
- Finally, subtract 6:
-20 - 6 = -26
Final Result
The value of the expression 3.2 - 6x + 4a + 3b is -26.
