Algebra I Recipe: Literal Equations (Formulas)
By G Redden
- Follow the same steps for solving equations as in the lesson Sec. 3.3.
- Letter(s) not being solved for get treated like actual numbers.
- The value of the variable being solved for is not a numerical value but an algebraic expression.
1.
solve for r: r - s = t
2.
solve for x: ax + b = c
3.
solve for y: 3y = x
4.
solve for y: x = ½(y + 4)
5.
solve for r: C = 2pr
6.
solve for h: V = (1/3)pr2h
7.
solve for b: A = ½bh
8.
solve for b2: A = ½(b1 + b2)h
