Question

Q. 42. If 4a + 3 = 15, then find the value of '2a'.
(1) 9
(2) 3
(3) 6
(4)5
how you solve this​

Answer 1

Step-by-step explanation:

4a + 3 = 15

4a = 12

a = 3

2a = 2 * 3

2a = 6

Answer 2

Answer:

I think you meant find the value of 4a

4a= 15-3

4a = 12

$a = \frac{12}{4}$

Therefore a=3

If you meant find 2a, then

2a + 3 = 15

2a = 15-3

2a = 12

$a = \frac{12}{2}$

a = 6
