2.8 – Literal Equations and Dimensional Analysis

Ex. 1 Solve 4m – 3n = 8 for m.

Ex. 1 Solve 4m – 3n = 8 for m. *Get m by itself!

Ex. 1 Solve 4m – 3n = 8 for m. *Get m by itself! 4m – 3n = 8 + 3n + 3n

Ex. 1 Solve 4m – 3n = 8 for m. Get m by itself
Ex. 1 Solve 4m – 3n = 8 for m. *Get m by itself! 4m – 3n = 8 + 3n + 3n 4m = 8 + 3n

Ex. 1 Solve 4m – 3n = 8 for m. Get m by itself
Ex. 1 Solve 4m – 3n = 8 for m. *Get m by itself! 4m – 3n = 8 + 3n + 3n 4m = 8 + 3n 4 4

Ex. 1 Solve 4m – 3n = 8 for m. Get m by itself
Ex. 1 Solve 4m – 3n = 8 for m. *Get m by itself! 4m – 3n = 8 + 3n + 3n 4m = 8 + 3n 4 4 m = 8 + 3n 4

Ex. 2 Solve 3x – 2y = x + 5 for x.

Ex. 2 Solve 3x – 2y = x + 5 for x. *Get x by itself!

Ex. 2 Solve 3x – 2y = x + 5 for x. Get x by itself
Ex. 2 Solve 3x – 2y = x + 5 for x. *Get x by itself! 3x – 2y = x + 5 -x -x

Ex. 2 Solve 3x – 2y = x + 5 for x. Get x by itself
Ex. 2 Solve 3x – 2y = x + 5 for x. *Get x by itself! 3x – 2y = x + 5 -x -x 2x – 2y = 5

Ex. 2 Solve 3x – 2y = x + 5 for x. Get x by itself
Ex. 2 Solve 3x – 2y = x + 5 for x. *Get x by itself! 3x – 2y = x + 5 -x -x 2x – 2y = 5 + 2y + 2y

Ex. 2 Solve 3x – 2y = x + 5 for x. Get x by itself
Ex. 2 Solve 3x – 2y = x + 5 for x. *Get x by itself! 3x – 2y = x + 5 -x -x 2x – 2y = 5 + 2y + 2y 2x = 5 + 2y

Ex. 2 Solve 3x – 2y = x + 5 for x. Get x by itself
Ex. 2 Solve 3x – 2y = x + 5 for x. *Get x by itself! 3x – 2y = x + 5 -x -x 2x – 2y = 5 + 2y + 2y 2x = 5 + 2y 2 2

Ex. 2 Solve 3x – 2y = x + 5 for x. Get x by itself
Ex. 2 Solve 3x – 2y = x + 5 for x. *Get x by itself! 3x – 2y = x + 5 -x -x 2x – 2y = 5 + 2y + 2y 2x = 5 + 2y 2 2 x = 5 + 2y 2
