Formula Rearrangement • Solve a formula for a specified variable.
+ 4 + 4 + r + r 2 2 kk m + r x = k Solving Equations and Formula Rearrangement Solve each of the following for x. 2x – 4 = 16 kx – r = m; solve for x 2x = 20 kx = m + r x = 10
A BCD = CD CD A = B CD Solving for a Specified Variable EXAMPLE 1 Solving for a Specified Variable Solve A = BCD for B. A = BCD Divide by CD.
– b – b y – b m x = x x y – b m = x Solving for a Specified Variable EXAMPLE 2 Solving for a Specified Variable Solve y = m x + b for m. y = m x + b Subtract b. y – b = m x Divide by x.
Solve y = b h for b. y = b h 2y = b h 2 1 1 1 1 2 2 2 2y 2y b h b = = h h h Solving for a Specified Variable EXAMPLE 3 Solving for a Specified Variable Multiply by 2. 2y = b h Divide by h.
