The answer is
Explanation:
For this equation, the variable is being multiplied by
In this case, the variable is being multiplied, so the inverse operation of multiplication is division. Now, you have to divide the left side by
Explanation:
First and foremost, an equation has to 'balance'. This means that the overall value of the left hand side must be the same as that of the right hand side.
Example: 2 = 2 is true; 2 = 3 is not balanced so is false
For addition or subtraction: what you wish to move to the other side of the = you change to 0
Example: 6 = 6
Subtract 2 from both sides
For multiply or divide: what you do to move to the other side of = you change it to 1. As demonstrated in the solution to this question.

Given:
Multiply both sides by (-1) this changes the signs
Moving the 4 to the other side: divide both sides by
