Question

Solve the following equation: 3x + 6 = 9​

Answer 1

x=1

Explanation:

Subtract 6 from both sides of the equation, leaving 3x=3.

We put both sides over 3 to divide.

We are left with x=3

To test this, we substitute x with 1.

3(1)+6=9

3+6=9

9=9

Answer 2

Explanation:

3x+6=9

3x=9-6

3x=2

x=1.5
