Algebra I Recipe: Literal Equations (Formulas)
Solving Literal Equations
  1. Follow the same steps for solving equations as in the lesson Sec. 3.3.
  2. Letter(s) not being solved for get treated like actual numbers.
  3. The value of the variable being solved for is not a numerical value but an algebraic expression.
solve for r: r - s = t
solve for x: ax + b = c
solve for y: 3y = x
solve for y: x = ½(y + 4)
solve for r: C = 2pr
solve for h: V = (1/3)pr2h
solve for b: A = ½bh
solve for b2: A = ½(b1 + b2)h
