when 7 is added to 3 times a number, the sum is multiplied by 2 and 15 is subtracted what is the final answer

2(3x+7) -15

Step-by-step explanation:

Let x = unknown number

7 is added to 3 times a number

3x+7

Multiply the sum by 2

2(3x+7)

Subtract 15

2(3x+7) -15

Let the required number be " x "

Now, 7 is added to 3 times a number : (3x + 7)

Next, the sum is multiplied by 2 : 2(3x + 7)

And then, 15 is substracted from it : 2(3x + 7) - 15

do you mean add both of the equations together

because if you do the answer is 10x-5
