Evaluate 4a + 7b + 3a – 2b for a = 4 and b = 3.

57

43

48

41

2nd Option is correct that is 43.

Step-by-step explanation:

We are given with an Expression,

4a + 7b + 3a - 2b

We need to find the value of the given expression for a = 4 and b = 3.

To find the value of the expression. We must simplify it first.

Consider,

4a + 7b + 3a - 2b

= 4a + 3a + 7b - 2b

= ( 4 + 3 )a + ( 7 - 2 )b

= ( 7 )a + ( 5 )b

= 7a + 5b

Now we just substitute the given value of a and b in above expression for find its value.

= 7 × 4 + 5 × 3

= 28 + 15

= 43

Therefore, 2nd Option is correct that is 43.
