Solving Literal Equations & Inequalities - Practice Day

Solving Literal Equations

Algebra 1

​Literal Equations

​Literal Equations are just like solving a normal equation, however they mostly consist of variables and not many numbers

​

​Treat literal equations the same way - cancel terms to get the variable by itself using INVERSE OPERATIONS

Multiple Choice

IR = V (solve for R) 

• R = IV

• R = ^I/_V

• R = ^V/_I

• R = V - I

Multiple Choice

Solve: y = mx + b , for b

• y - mx = b

• y + mx = b

• ^y/_mx = b

• y + mx = -b

Multiple Choice

pV = nRT solve for R

• R= pV/nT

• R= p/n + V/T

• R= pV - nT

• R= (pV-n)/T
