Literal Equations

A literal equation is an equation that involves two or more variables. It is often solved for one variable in terms of the others.

To isolate a variable means to manipulate the equation so that the variable is on one side of the equation by itself.

The same operation must be performed on both sides of an equation to maintain equality.

Subtract 2x from both sides to get 3x + 9 = -3, then subtract 9 from both sides to get 3x = -12, and finally divide by 3 to find x = -4.

To solve for X, you need to rearrange the equation to isolate X on one side.

The slope (M) represents the rate of change of Y with respect to X.

The Y-intercept (B) represents the value of Y when X is 0.

You can substitute your solution back into the original equation to see if both sides are equal.

Rearranging equations helps to isolate variables and solve for unknowns.
