21
1. 6 + 3x = 15​

Answer 1

3

Step-by-step explanation:

3x=15-6

3x=9

x=9/3

x=3

Answer 2

Answer:

The answer is 3 because,

Step-by-step explanation:

6+3x=15

So now we need the value of x only ,

So we are subtracting now 6 from 15 (15-6)

subtracting 15-6 we get 9

now the equation will be 3x = 9

Now also we need only the value of x so we bring 3 to the right side so now the equation is

x = 9/3 Cancelling 9/3 gives 3.

Therefore 3 is the answer.
