Question

Q5. Solve the following equations .
(0)
2b + 9 = 15
(ii
)
2a - 4 = 6
pls tell answer with explanation ​

Answer 1

Answer:

2b+9 = 15

2b = 15-9

2b = 6

b = 6/2

b = 3

2a-4 = 6

2a = 6 + 4

2a = 10

a = 10/2

a = 5

please follow me

Answer 2

i) 2b + 9 = 15

2b = 15 -9 = 6 (transposition method)

b = 6/2 = 3 (transposition method)

ii) 2a - 4 = 6

2a = 6 + 4 = 10

a = 10/2 = 5

we use transposition method to solve sums like these.
