Given :
a = 3, b = 2
To find : 7a - 3b
Solution :
• To find the value of 7a - 3b, we first need to multiply a by 7 and b by 3.
• To find the value of 7a - 3b, we first need to multiply a by 7 and b by 3.
• Therefore, 7 × a = 7 × 3 = 21
3 × b = 3 × 2 = 6
• Now, subtracting 3b from 7a, we get;
7a - 3b = 21 - 6 = 15
• Therefore, the value of 7a - 3b is equal to 15.
