Question

Solve the following equations and verify the answer
(a) 4(6a + 1)-3(4a + 3) = 31
​

Answer 1

Step-by-step explanation:

4(6a+1)-3(4a+3)=31

24a+1-(12a+3)=31

25a-15a=31

10a=31

a=31/10

Answer 2

Answer:

24a + 4 - 12a - 9 = 31

12a - 5 = 31

12a = 31 + 5

12a = 36

a = 36/12

a = 3

VERIFICATION :-

4 (6 (3) + 1) -3 (4 (3) + 3)

4 (18 + 1) - 3 (12 + 3)

4 (19) -3 (15)

76 - 45

31

Step-by-step explanation:

Therefore value of a is 3
