How do you distribute in an equation?

Back

To distribute means to multiply a term outside the parentheses by each term inside the parentheses. For example, in 3(2x + 4), you would multiply 3 by 2x and 3 by 4.

How do you isolate the variable in the equation 6(2x + 5) = -6?

Back

First, distribute the 6 to get 12x + 30 = -6, then subtract 30 from both sides to get 12x = -36, and finally divide by 12 to find x.

How do you check your solution for an equation?

Back

To check your solution, substitute the value of the variable back into the original equation to see if both sides are equal.

Front

What is the importance of the equal sign in an equation?

Back

The equal sign indicates that the expressions on both sides of the equation are equivalent, and it is crucial for maintaining balance when solving.
