Front

What is the first step in solving the equation 7x - 4 = 3 + 8x?

Back

The first step is to get all terms involving x on one side and constant terms on the other side. This can be done by subtracting 7x from both sides.

Front

How do you isolate the variable in the equation 5x - 14 = 8x + 4?

Back

To isolate the variable, you can first move all x terms to one side by subtracting 5x from both sides, resulting in -14 = 3x + 4.

Front

What does it mean to combine like terms in an equation?

Back

Combining like terms means to add or subtract terms that have the same variable raised to the same power, simplifying the equation.

Front

What is the importance of keeping the equation balanced when solving?

Back

Keeping the equation balanced means that whatever operation you perform on one side must also be performed on the other side to maintain equality.
