Question

3(x+7)=-15 I need a clear explanation of visual representation instead of the answer itself

Answer 1

Answer:

x = -7

Step-by-step explanation:

3(x+7)  = -15

First, distributive property. Therefore, you multiply 3 with x and 7

3x + 21 = -15

Then, you need x to be isolated. So you will have to -21 from +21 on both sides of the equation to make it balanced.

3x + 21 = -15

     -21     -21    (21 will be canceled from the left side of the equation)

3x = -35

Lastly, you need to divide 3 from both sides of the equation, as 3 is multiplied with x.

3x = -35

3        3    (3 will be canceled from the left side of the equation)

x = -7
