Answer 2

Answer:

We can do this by 2 ways...

1) TRANSPOSING METHOD -

7a + 15 = 19

7a = 19 - 15

7a = 14

a = 14/7

a= 2

Therefore, your answer is 2

--------------------------------------------------

2) SYSTEMATIC METHOD -

7a + 15 = 19

7a + 15 - 15 = 19 - 15 ( Subtracting 15 on both sides)

7a = 14

7a ÷ 7 = 14/7 (Dividing 7 on both sides )

a = 2

Therefore your answer is 2
