Answer :
Given
x = 3, y = 7
To find out:
The value of 20 + 2(3y - 4x)
Solution:
- 20 + 2(3y - 4x)
Let us put the value of x and y as given.
- = 20 + 2 (3 × 7 - 4 × 3)
Now, solve the bracket portion. First do the multiplication.
- = 20 + 2 (21 - 12)
Now, subtract.
- = 20 + 2 (9)
Multiply 9 with 2.
- = 20 + 18
Finally, add the two.
- = 38
Answer:
38
