What does cross multiply mean?
Cross multiplying is a method used to solve equations involving fractions. It involves multiplying the numerator of one fraction by the denominator of the other fraction, and vice versa. For example, in the equation (\frac{a}{b} = \frac{c}{d}), cross multiplying yields (a \cdot d = b \cdot c). This technique helps eliminate the fractions and simplifies the equation for easier solving.
True or false Are all the techniques and methods used to solve linear equations may be used to solve rational equations?
False. While some techniques used for solving linear equations, such as isolating variables and cross-multiplying, can also be applied to rational equations, not all methods are applicable. Rational equations often require additional steps, such as finding a common denominator and checking for extraneous solutions, due to the presence of variables in the denominator. Thus, the approach to solving rational equations can be more complex than that for linear equations.

Why do you cross multiply fractions?
Cross multiplying fractions is a method used to compare two fractions or solve equations involving them. By multiplying the numerator of one fraction by the denominator of the other, you create a simple equation that can be solved easily. This technique helps in determining whether two fractions are equal or in finding unknown values in proportion problems without dealing directly with the fractions themselves.
How solve systems of equations and inequalities using elimination?
To solve systems of equations using elimination, first align the equations and manipulate them to eliminate one variable. This is often done by multiplying one or both equations by suitable constants so that the coefficients of one variable are opposites. After adding or subtracting the equations, solve for the remaining variable, then substitute back to find the other variable. For inequalities, the same elimination process applies, but focus on determining the range of values that satisfy the inequalities.

In order to solve the following system of equations by addition could you do before adding the equations so that one variable will be eliminated when you add them?
Yes, you can manipulate the equations before adding them to eliminate one variable. This can be done by multiplying one or both equations by a suitable coefficient so that the coefficients of one variable become opposites. Once the coefficients are aligned, you can add the equations together, resulting in the elimination of that variable, making it easier to solve for the remaining variable.
How can you use a graph to solve systems of equations?
You can use a graph to solve systems of equations by plotting the two equations to see where they intersect
What are the steps to the elimination method?
The elimination method involves three main steps to solve a system of linear equations. First, manipulate the equations to align the coefficients of one variable, either by multiplying one or both equations by suitable constants. Next, add or subtract the equations to eliminate that variable, simplifying the system to a single equation. Finally, solve for the remaining variable, and substitute back to find the value of the eliminated variable.
How do you solve trigonometric equations?
The answer depends on the nature of the equations.
