Rearranging Equations

Rearranging equations involves manipulating an equation to isolate a specific variable on one side, making it easier to solve for that variable.

To solve for a variable means to express that variable in terms of other variables or constants, allowing you to find its value.

Rearranging gives $$y = \frac{1}{5}x - 4$$ .

The slope-intercept form is $$y = mx + b$$ , where m is the slope and b is the y-intercept.

Rearranging gives $$x = \frac{y - b}{m}$$ .

The area of a rectangle is given by $$A = lw$$ , where l is the length and w is the width.

Rearranging gives $$w = \frac{A}{l}$$ .

In the formula, p represents the principal amount in a financial context.

Rearranging gives $$p = \frac{I}{rt}$$ .

The first step is to identify the variable you want to isolate and determine which operations need to be reversed.
