1. TRANSFORMING FORMULA VARIABLES ON BOTH SIDES

2. LITERAL EQUATION "solving literal equations" is another way of saying, "taking an equation with lots of letters, and solving for one letter in particular."

3. Examples of LITERAL EQUATIONS d= rt d=distancer=ratet=time A= ½(bh) A=area of a triangle b=baseh=height P= 2w + 2l P=perimeterw=widthl=length

4. Solving Literal Equations d= rt d=distancer=ratet=time Solve for t d= rt r d= t r t =d r r Solve for r d= rt t d= t t r =d t t

5. A= ½(bh) A=area of a triangle b=baseh=height Solve for b A = ½ (bh) (2)(2) 2A = (bh) hh 2A = b h b = 2A h

6. A= ½(bh) A=area of a triangle b=baseh=height Solve for h h = 2A b YOUR TURN!

7. P= 2w + 2l P=perimeterw=widthl=length Solve for l P = 2w + 2l -2w-2w P -2w = 2l 2 2 P -2w = l 2

8. Solve the following literal equations and write each step made m = ⅓ (t + e) Solve for t t= 3m-e b = 6k + 4d Solve for d d=(b-6k) 4

9. Homework X = 4a + s Solve for a X = 4a + s Solve for s m = ⅓ (t + e) Solve for t h = ⅓k - w Solve for k h = ⅓k - w Solve for w b = 6k + 4d Solve for d a= x - s 4 s= x - 4a t= 3m-e k=3(h+w) w=h - ⅓k d=(b-6k) 4
