Answer:
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.
